For a calculation that has only one mathematical operation with two numbers, it is a simple case of either adding, subtracting, multiplying or dividing to find your answer.

But what about when there are several numbers, and different operations? Maybe you need to divide and multiply, or add and divide. What do you do then?

Fortunately, mathematics is a logic-based discipline. As so often, there are some simple rules to follow that help you work out the order in which to do the calculation. These are known as the ‘Order of Operations’.

### Rules of Ordering in Mathematics - BODMAS BODMAS is a useful acronym that tells you the order in which you solve mathematical problems. 5 2 3 important that you follow the rules of BODMAS, because without it your answers can be wrong.

The BODMAS acronym is for:

• Brackets (parts of a calculation inside brackets always come first).
• Orders (numbers involving powers or square roots).
• Division.
• Multiplication.
• Subtraction.

BODMAS, BIDMAS or PEMDAS?

You may often see BIDMAS instead of BODMAS. They are exactly the same. In BIDMAS, the ‘I’ refers to Indices, which are the same as Orders. For more information, see our page on Special Numbers and Concepts.

PEMDAS

PEMDAS is commonly used the in USA it works 5 2 3 same as BODMAS. The PEMDAS acronym is:

Parentheses,

Exponents (powers and roots),

Multiplication and Division,

Further Reading from Skills You Need The Skills You Need Guide to Numeracy This four-part guide takes you through the basics of numeracy from arithmetic to algebra, with stops in between at fractions, decimals, geometry and statistics.

Whether you want to brush up on 5 2 3 basics, or help your children with their learning, this is the book for you.

### Brackets

#### Example:

4 × (3 + 2) = ?

You need to do the operation, inside the brackets first, 3 + 2, then multiply the answer by 4.

3 + 2 = 5.
4 × 5 = 20

If you ignored the brackets and did your calculation from left to right 4 × 3 + 2 you would get 14. You can see how the brackets make a difference to the answer.

### Orders

Do anything involving a power or a square root next (these are also known as orders), again working from left to right if there is more than one.

#### Example:

32 + 5 = ?

You need to calculate the power first, before you can add 5.

32 = 3 × 3 = 9
9 + 5 = 14

### Division and Multiplication

Once you have done any parts of the calculation involving brackets or powers the next step is division and multiplication.

Multiplication and division rank equally, so you work from left to right in the sum, doing each operation in the order in which it appears.

#### Example:

6 ÷ 2 + 7 × 4 = ?

You need to do division and multiplication first, but you have one of each.

Start from the left and work across to the right, which means that you start with 6 ÷ 2 = 3. Then do the multiplication, 7 × 4 = 28.

Your calculation is now 3 + 28.

See our pages: Multiplication and Division for more.

The final step is to calculate any addition or subtraction. Again, subtraction and addition rank equally, and you simply work from left to right.

#### Example:

4 + 6 − 7 + 3 = ?

You start on the left and work your way across.

4 + 6 = 10
10 − 7 = 3
3 + 3 = 6

See our pages: Addition and Subtraction for more.

### Bringing It All Together

This final worked example includes all elements of BODMAS.

#### Example:

4 + 82 × (30 ÷ 5) = ?

30 ÷ 5 = 6
This gives you 4 + 82 × 6 = ?

Then calculate the orders - in this case the square of 8.

82 = 64
Your calculation is now 4 + 64 × 6

Then move to the multiplication 64 × 6 = 384

Finally perform the addition. 4 + 384 = 388

### BODMAS Test Questions

The rules of BODMAS are easiest to understand with some practice and examples.

Try these calculations yourself and then open up the box (click on the + symbol to the left) to see the workings and answers.

There are no brackets or orders in this calculation.

1. Multiplication comes before addition, so start with 20 × tcf bank chicago routing number = 60.
2. The calculation now reads 3 heritage federal credit union newburgh 60

2. The calculation now reads 25 − 5 ÷ 5
3. Division comes before subtraction. 5 ÷ 5 = 1.
4. The calculation now reads 25 − 1

2. The calculation now reads 10 + 6 × 11
3. Multiplication comes before addition. 6 × 11 = 66.
4. The calculation now reads 10 + 66.

When there is no sign like in this calculation, the operator is a multiplication, the same as writing 5 × (3 + 2) + 52.

1. Complete the calculation inside the brackets first: (3 + 2) = 5.
2. That gives you 5 × 5 + 52.
3. The next step is orders, in this case, the square. 52 = 5 × 5 = 25. Now you have 5 × 5 + 25.
4. Division and multiplication come before addition and subtraction, so your next step is 5 × 5 = 25. Now the calculation reads 25 + 25 = 50.

The answer is 5 2 3 one has everything! But don’t panic. BODMAS still applies, and all you have to do is unpick the calculation.

2. The calculation now reads 311 – 550 ÷ 52 + 10
3. Next, orders or powers. In this case, that’s 52 = 25.
4. The calculation now reads 311 – 550 ÷ 25 + 10
5. Next, division and multiplication. There is no multiplication, but the division is 550 ÷ 25 = 22.
6. Now the calculation reads 311 – 22 + 10.
7. Although you still have two operations left, addition and subtraction rank equally, so you just go from left to right. 311 – 22 = 289, and 289 + 10 = 299.

Problems like this often do the rounds on social media sites, with captions like '90% of people get this wrong'. Just follow the rules of BODMAS to get the correct answer.

1. There are no brackets or orders so start with division and multiplication.
2. 7 ÷ 7 = 1 and 7 × 7 = 49.
3. The calculation now reads 7 + 1 + 49 – 7
4. Now do the addition and subtraction. 7 + 1 + 49 = 57 – 7 = 50

### How Did You Do?

Hopefully you managed to get all the answers right. If not, go back and review where you went wrong, and read over the rules again.

The more you practise, the easier BODMAS becomes and eventually you won’t even have to think about it.

## Exponents

The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication,
so 82 = 8 × 8 = 64

In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"

Exponents are also called Powers or Indices.

Some more examples:

### Example: 53 = 5 × 5 × 5 = 125

• In words: 53 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"

### Example: 24 = 2 × 2 × 2 × 2 = 16

• In words: 24 could be called "2 to the fourth power" or "2 to the power 4" or simply "2 to the 4th"

Exponents make it easier to write and use many multiplications

Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9

You can multiply any number by itself as many times as you want using exponents.

Try here:

algebra/images/exponent-calc.js

So in general:

 an tells you to multiply a by itself, so there are n of those a's: ### Another Way of Writing It

Sometimes people use the ^ symbol (above the 6 on your keyboard), as it is easy to type.

Example: 2^4 is the same as 24

### Negative Exponents

Negative? What could be the opposite of multiplying? Dividing!

So we divide by the number each time, which is the same as multiplying by 1number

Example: 8-1 =18 = 0.125

We can continue on like this:

Example: 5-3 = 15 × 15 × 15 = 0.008

But it is often easier to do it this way:

5-3 could also be calculated like:

15 × 5 × 5 = 153 = 1125 = 0.008

### Negative? Flip the Positive! That last example showed an easier way to handle negative exponents:Calculate the positive exponent (an)Then take the Reciprocal (i.e. 1/an)

More Examples:

Negative Exponent Reciprocal of
Positive Exponent
4-2 = 1 / 42 = 1/16 = 0.0625
10-3 = 1 / 103 = 1/1,000 = 0.001
(-2)-3 = 1 / (-2)3 = 1/(-8) = -0.125

### What if the Exponent is 1, or 0?

 1 If the exponent is 1, then you just have the number itself (example 91 = 9) 0 If the exponent is 0, then you get 1 (example 90 = 1) But what about 00 ? It could be either 1 or 0, and so people say it is "indeterminate".

### It All Makes Sense

If you look at that table, you will see that positive, zero or negative exponents are really part of the same (fairly simple) pattern:

 Example: Powers of 5 2 3. etc. 52 5 × 5 25 51 5 5 50 1 1 5-1 15 0.2 5-2 15 × 15 0.04 . etc.

### Be Careful About 5 2 3 avoid confusion, use parentheses () in cases like this:With () :(−2)2 = (−2) × (−2) = 4Without () :−22 = −(22) = −(2 × 2) = −4With () :(ab)2 = ab × abWithout () :ab2 = a × (b)2 = a × b × b305, 1679, 306, 1680, 1077, 1681, 1078, 1079, 3863, 3864Laws of ExponentsFractional Bb gun sniper scope of 10DecimalsMetric Numbers

## How to Find the General Term of Sequences

Ray is a licensed engineer in the Philippines. He loves to write about mathematics and civil engineering.

### What Is a Sequence?

A sequence is a function whose domain is an ordered list of numbers. These numbers are positive integers starting with 1. Sometimes, people mistakenly use the terms series and sequence. A sequence is a set of positive integers while series is the sum of these positive integers. The denotation for the terms in a sequence is:

a1, a2, a3, a4, an. . .

Finding the nth term of a sequence is easy given a general equation. But doing it the other way around is a struggle. Finding a general equation for a given sequence requires a lot central illinois bank hours thinking and practice but, learning the specific rule guides you in discovering the general equation. In this article, you will learn how to induce the patterns of sequences and write the general term when given the first few terms. There is a step-by-step guide for you to follow and understand the process and provide you with clear and correct computations.

### What Is an Arithmetic Sequence?

An arithmetic series is a series of ordered numbers with a constant difference. In an arithmetic sequence, you will observe that each pair of consecutive terms differs by the same amount. For example, here are the first five terms of the series.

3, 8, 13, 18, 23

Do you notice a special pattern? It is obvious that each number after the first is five more than the preceding term. Meaning, the common difference of the sequence is five. Usually, the formula for the nth term of an arithmetic sequence whose first term is a1 and whose common difference is d is displayed below.

an = a1 + (n - 1) d

### Steps in Finding the General Formula of Arithmetic and Geometric Sequences

1. Create a table with headings n and an where n denotes the set of consecutive positive integers, and an represents the term corresponding to the positive integers. You may pick only the first five terms of the sequence. For example, tabulate the series 5, 10, 15, 20, 25. . .

2. Solve the first common difference of a. Consider the solution as a tree diagram. There are two conditions for this step. This process applies only to sequences whose nature are either linear or quadratic.

Condition 1: If the first common difference is a constant, use the linear equation ax + b = 0 in finding the general term of the sequence.

a. Pick two pairs of numbers from the table and form two equations. The value of n from the table corresponds to the x in the linear equation, and the value of an corresponds to the 0 in the linear equation.

a(n) + b = an

b. After forming the two equations, calculate a and b using the subtraction method.

c. Substitute a and b to the general term.

d. Check if the general term is correct by substituting the values in the general equation. If the general term does not meet the sequence, there is an error with united petsafe phone number calculations.

Condition 2: If the first difference is not constant and the second difference is constant, use the quadratic equation ax2 + b(x) + c = 0.

a. Pick three pairs of numbers from the table and form three equations. The value of n from the table corresponds to the x in the linear equation, and the value of an corresponds to the 0 in the linear equation.

an2 + b(n) + c = an

b. After forming the three equations, calculate a, b, and c using the subtraction method.

c. Substitute a, b, and c to the general term.

d. Check if the general term is correct by substituting the values in the general equation. If the general term does not meet the sequence, there is an error with your calculations.

### Problem 1: General Term of an Arithmetic Sequence Using Condition 1

Find the general term of the sequence 7, 9, 11, 13, 15, 17. .

### Solution

a. Create a table of an and n values.

b. Take the first difference of an.

c. The constant difference is 2. Since the first difference is a constant, therefore the general term of the given sequence is linear. Pick two sets of values from the table and form two equations.

General Equation:

an + b = an

Equation 1:

at n = 1, a1 = 7

a (1) + b = 7

a + b = 7

Equation 2:

at n = 2a2 = 9

a (2) + b = 9

2a + b = 9

d. Subtract the two equations.

(2a + b = 9) - (a + b = 7)

a = 2

e. Substitute the value of a = 2 in equation 1.

a + b = 7

2 + b = 7

b = 7 - 2

b = 5

f. Substitute the values a = 2 and b = 5 in the general equation.

an + b = an

2n + 5 = an

g. Check the general term by substituting the values into the equation.

an = 2n + 5

a1= 2(1) + 5 = 7

a2= 2(2) + 5 = 9

a3= 2(3) + 5 = 11

a4= 2(4) + 5 = 13

a5= 2(5) + 5 = 15

a6= 2(6) + 5 = 17

Therefore, the general term of the sequence is:

an = 2n + 5

### Problem 2: General Term of Arithmetic Sequence Using Condition 2

Find the general term of the sequence 2, 3, 5, 8, 12, 17, 23, 30. .

### Solution

a. Create a table of an and 5 2 3 values.

b. Take the first difference of an. If the first difference of an is not constant, take the second.

c. The second difference is 1. Since the second difference is a constant, therefore the general term of the given sequence is quadratic. Pick three sets of values from the table and form three equations.

General Equation:

an2 + b(n) + c = an

Equation 1:

at n = 1, a1 = 2

a (1) + b (1) + c = 2

a + b + c = 2

Equation 2:

at n = 2, a2 = 3

a (2)2 + b (2) + c = 3

4a + 2b + c = 3

Equation 3:

at n = 3, a2 = 5

a (3)2 + b (3) + c = 5

9a + 3b + c = 5

d. Subtract the three equations.

Equation 2 - Equation 1: (4a + 2b + c = 3) - (a + b + c = 2)

Equation 2 - Equation 1: 3a + b = 1

Equation 3 - Equation 2: (9a + 3b + c = 5) - (4a + 2b + c = 3)

Equation 3 - Equation 2: 5a + b = 2

(5a + b = 2) - (3a + b = 1)

2a = 1

a = 1/2

e. Substitute the value of a = 1/2 in any of the last two equations.

3a + b = 1

3 (1/2) + b = 1

b = 1 - 3/2

b = - 1/2

a + b + c = 2

1/2 - 1/2 + c = 2

c = 2

f. Substitute the values a = 1/2, b = -1/2, and c = 2 in the general equation.

an2 + b(n) + c define straight ally an

(1/2)n2 - (1/2)(n) + 2 = an

g. Check the general term by substituting the values into the equation.

(1/2)n2 - (1/2)(n) + 2 = an

an = 1/2 (n2 - n + 4)

a1 = 1/2 (12 - 1 + 4) = 2

a2 = 1/2 (22 - 2 + 4) = 3

a3 = 1/2 (32 - 3 + 4) = 5

a4 = 1/2 (42 - 4 + 4) = 8

a5 = 1/2 (52 - 5 + 4) = 12

a6 = 1/2 (62 - 6 + 4) = 17

a7 = 1/2 (72 - 7 + 4) = 23

Therefore, the general term of the sequence how to cancel walmart pickup order = 1/2 (n2 - n + 4)

### Problem 3: General Term of Arithmetic Sequence Using Condition 2

Find the general term for the sequence 2, 4, 8, 14, 22. . .

### Solution

a. Create a table of an and n values.

b. Take the first and second difference of an.

c. The second difference is 2. Since the second difference is a constant, therefore the general term of the given sequence is quadratic. Pick three sets of values from the table and form three equations.

General Equation:

an2 + b(n) + c = an

Equation 1:

at n = 1, a1 = 2

a (1) + b (1) + c = 2

a + b + c = 2

Equation 2:

at n = 2, a2 = 4

a (2)2 + b (2) + c = 4

4a + 2b + c = 4

Equation 3:

at n = 3, a2 = 8

a (3)2 + b (3) + c = 8

9a + 3b + c = 8

d. Subtract the three equations.

Equation 2 - Equation 1: (4a + 2b + c = 4) - (a + b + c = 2)

Equation 2 - Equation 1: 3a + b = 2

Equation 3 - Equation 2: (9a + 3b + c = 8) - (4a + 2b + c = 4)

Equation 3 - Equation 2: 5a + b = 4

(5a + b = 4) - (3a + b = 2)

2a = 2

a = 1

e. Substitute the value of a = 1 in geld overmaken naar creditcard ics abn amro of the last two equations.

3a + b = 2

3 (1) + b = 2

b = 2 - 3

b = - 1

a + b + c = 2

1 - 1 + c = 2

c = 2

f. Substitute the values a = 1, b = -1, and c = 2 in the general equation.

an2 + b(n) + c = an

(1)n2 - (1)(n) + 2 = an

n2 - n + 2 = an

g. Check the general term by substituting the values into the equation.

n2 - n + 2 = an

a1 = 12 - 1 + 2 = 2

a2 = 22 - 2 + 2 = 4

a3 = 32 - 3 + 2 = 8

a4 = 42 - 4 + 2 = 14

a5 = 52 - 5 + 2 = 22

Therefore, the general term of the sequence is:

an = n2 - n + 2

Question: How to find general pattern of 3/7, 5/10, 7/13.?

Answer: For fractions, you can separately analyze the pattern in the numerator and the denominator.

For the numerator, we can see that the pattern is by adding 2.

3

3 + 2 = 5

5 + 2 = 7

or by adding multiples of 2

3

3 + 2 = 5

3 + 4 = 7

Therefore the general term for the numerator is 2n + 1.

For the denominator, we can observe that the pattern is by adding 3.

7

7 + 3 = 10

10 + 3 = 13

Or by adding multiples of 3

7

7 + 3 = 10

7 + 6 = 13

Therefore, the pattern for the denominator is 3n + 4.

Combine the two patterns and you'll come up with (2n + 1) / (3n + 4) which is the final answer.

23 - 18 = 5

Therefore the common difference is 5. The sequence is done by adding 5 to the previous term. Recall that the formula for the arithmetic progression is an = a1 + (n - 1)d. Given a1 = 8 and d = 5, substitute the values to the general formula.

an = a1 + (n - 1)d

an = 8 + (n - 1) (5)

an = 8 + 5n - 5

an = 3 + 5n

Therefore, the general term of the arithmetic sequence is an = 3 + 5n

Question: How to find general term of sequence of -1, 1, 5, 9, 11?

Answer: I actually don't get the sequence really well. But my instinct says it goes like this.

-1 + 2 = 1

1 + 4 = 5

5 +4 = 9

9 + 2 = 11

+2, +4, +4, +2, +4, +4, +2, +4, +4

Question: How to find the general term of 32,16,8,4,2.?

Answer: I believe each term (except the first term) is found by dividing the previous term by 2.

Question: How to find general term of sequence 1/2, 1/3, 1/4, 1/5?

Answer: You can observe that the only changing portion is the denominator. So, we can set the numerator as 1. Then the common difference of the denominator is 1. So, the expression is n+1.

The general term of the sequence is 1/(n+1)

Question: How to find general term of the sequence 1,6,15,28?

Answer: The general term of the sequence is n(2n-1).

Question: How to pay a simple mobile phone bill to find the general term of the sequence 1, 5, 12, 22 ?

Answer: The general term of the sequence 1, 5, 12, 22 is [n(3n-1)]/2.

### Video transcript

We're asked to multiply 5/6 times 2/3 and then simplify our answer. So let's just multiply these two numbers. So we have 5/6 times 2/3. Now when you're multiplying fractions, it's actually a pretty straightforward process. The new numerator, or the numerator of the product, is just the product of the two numerators, or your new top number is a product of the other two top numbers. So the numerator in our product is just 5 times 2. So it's equal to 5 times 2 over 6 times 3, which is equal to-- 5 times 2 is 10 and 6 times 3 is 18, so it's equal to 10/18. And you could view this as either 2/3 of 5/6 or 5/6 of 2/3, depending on how you want to think about it. And this is 5 2 3 right answer. It is 10/18, but when you look at these two numbers, you immediately or you might immediately see that they share some common factors. They're both divisible by 2, so if we want it in lowest terms, we want to divide them both by 2. So divide 10 by 2, divide 18 by 2, and you get 10 divided by 2 is 5, 18 divided by 2 is 9. Now, you could have essentially done this step earlier on. You could've done it actually before we did the multiplication. You could've done it over here. You could've said, well, I have a 2 in the numerator and I have something divisible by 2 into the denominator, so let me divide the numerator by 2, and this becomes a 1. Let me divide the denominator by 2, and this becomes a 3. And then you have 5 times 1 is 5, and 3 times 3 is 9. So it's really the same thing we did right here. We just did it before we actually took the product. You could actually do it right here. So if you did it right over here, you'd say, well, look, 6 times 3 is eventually going to be the denominator. 5 times 2 is eventually going to be the numerator. So let's divide the numerator by 2, so this will become a 1. Let's divide the denominator by 2. This is divisible by 2, so that'll become a 3. And it'll become 5 times 1 is 5 and 3 times 3 is 9. So either way you do it, it'll work. If you do it this way, you get to see the things factored out a little bit more, so it's usually easier to recognize what's divisible by what, or you could do it who sells usa today newspaper near me the end and put things in lowest terms.

## Fraction Calculator

Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Fields above the solid black line represent the numerator, while fields below represent the denominator.

### Big Number Fraction Calculator

Use this calculator if the numerators or denominators are very big integers. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of

, the numerator is 3, and the denominator is 8. A more illustrative example could 36 c to f a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified form (the provided calculator computes the simplification automatically). Below is an example using this method.

 + = + =
 EX: + = + = =

This process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own respective denominator) in the problem.

EX:
+ + =
 1×6×2 4×6×2
+
 1×4×2 6×4×2
+
 1×4×6 2×4×6
=
 + + = =

An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers.

 Multiples of 2: 2, 4, 6, 8 10, 12 Multiples of 4: 4, 8, 12 Multiples of 6: 6, 12

The first multiple they all share is 12, so this is the least common multiple. To complete an addition (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.

EX:
 + + = + +
=

### Subtraction:

Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification.

 – = – =
 EX: – = – = =

### Multiplication:

Multiplying fractions is fairly straightforward. Unlike adding and subtracting, it is not necessary to compute a common denominator in order to multiply fractions. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. If possible, the solution should be simplified. Refer to the equations below for clarification.

 EX: × = =

### Division:

The process for dividing fractions is similar to that for multiplying fractions. In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is simply

. When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction would therefore be. Refer to the equations below for clarification.
 / = × =
 EX: / = × = =

### Simplification:

It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms.

for example, is more cumbersome than. The calculator provided returns fraction inputs in both improper fraction form as well as mixed number form. In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor.

### Converting between fractions and decimals:

Converting from decimals to fractions is straightforward. It does, however, require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, and so on. Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, and simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 104, or 10,000. This would make the fraction

, which simplifies tosince the greatest common factor between the numerator and denominator is 2.

Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of 10) can be translated to decimal form using the same principles. Take the fraction

for example. To convert this fraction into a decimal, first convert it into the fraction of. Knowing that the first decimal place represents 10-1, can be converted to 0.5. If the fraction were insteadthe decimal would then be 0.05, and so on. Beyond this, converting fractions into decimals requires the operation of long division.

### Common Engineering Fraction to Decimal Conversions

In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below.

## 3. An Informal Introduction to Python¶

### 3.1.3. Lists¶

Python knows a number of compound data types, used to group together other values. The most versatile is the list, which can be written as a list of comma-separated values (items) between square brackets. Lists might contain items of different types, but usually the items all have the same type.

>>> squares=[1,4,9,16,25]>>> squares[1, 4, 9, 16, 25]

Like strings (and all other built-in sequence types), lists can be indexed and sliced:

>>> squares# indexing returns the item1>>> squares[-1]25>>> squares[-3:]# slicing returns a new list[9, 16, 25]

All slice operations return a new list containing the requested elements. This means that the following slice returns a shallow copy of the list:

>>> squares[:][1, 4, 9, 16, 25]

Lists also support operations like concatenation:

>>> squares+[36,49,64,81,100][1, 4, 9, 16, 25, 36, 49, 64, 81, 100]

Unlike strings, which are immutable, lists are a mutable type, i.e. it is possible to change their content:

>>> cubes=[1,8,27,65,125]# something's wrong here>>> 4**3# the cube of 4 is 64, not 65!64>>> cubes=64# replace the wrong value>>> cubes[1, 8, 27, 64, 125]

You can also add new items at the end of the list, by using the method (we will see more about methods later):

>>> cubes.append(216)# add the cube of 6>>> cubes.append(7**3)# and the cube of 7>>> cubes[1, 8, 27, 64, 125, 216, 343]

Assignment to slices is also possible, and this can even change the size of the list or clear it entirely:

>>> letters=['a','b','c','d','e','f','g']>>> letters['a', 'b', 'c', 'd', 'e', 'f', 'g']>>> # replace some values>>> letters[2:5]=['C','D','E']>>> letters['a', 'b', 'C', 'D', 'E', 'f', 'g']>>> # now remove them>>> letters[2:5]=[]>>> letters['a', 'b', 'f', 'g']>>> # clear the list by replacing all the elements with an empty list>>> letters[:]=[]>>> letters[]

The built-in function also applies to lists:

>>> letters=['a','b','c','d']>>> len(letters)4

It is possible to nest lists (create lists containing other lists), for example:

>>> a=['a','b','c']>>> n=[1,2,3]>>> x=[a,n]>>> x[['a', 'b', 'c'], [1, 2, 3]]>>> x['a', 'b', 'c']>>> x'b'

## What is 2/3 of 5?

In this article, we'll show you m words for kindergarten how to calculate 2/3 of 5 so you can work out the fraction of any number quickly and easily! Let's get to the math!

Want to quickly learn or show students how to convert 2/3 of 5? Play this very quick and fun video now!

You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the add visa gift card to cash app now that we've converted 5 into a fraction, to work out the answer, we put the fraction 2/3 side by side with our new fraction, 5/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

2 x 5/3 x 1=10/3

As you can see in this case, the numerator is higher than the denominator. What this means is that we can simplify the answer down to a mixed number, also known as a mixed fraction.

To do that, we need to convert the improper fraction to a mixed fraction. We won't explain that in detail here because we have another article that already covers it for 10/3. Click here to find out how to convert 10/3 to a mixed fraction.

The complete and simplified answer to the question what is 2/3 of 5 is:

3 1/3

Hopefully this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.
