## Definition:

Percents are the result of expressing numbers as a part of 100.

The word percent means per hundred.

**percent sign**, %, is used to indicate the number of parts out of 100 parts.

For example: 10% is equivalent to 10/100 fraction

15% is equivalent to ^{15}⁄_{100} fraction

20% is equivalent to ^{20}⁄_{100} fraction

A percentage was form by dividing the value by the total value and then multiply the resultant by 100.

Formula: (^{Value}⁄_{Total value}) × 100

Example: ^{3}⁄_{4} x 100 = 0.75 x 100 = 75%

## How to find the percentage of a number:

We can use different formulas to calculate the percentage of a number, such as:

**1.**

We represent P% of number by X, while X is required number :

P% of Number = X

When remove the % sign, we have a formula: ^{P}⁄_{100} x Number = X

Example: Find out 15% of 60

We have:

15% of 60 = X

^{15}⁄_{100} x 60 = X

X = 0.15 x 60

X = 9

**2.**

Know that: X is the required number

By using the equation: Total value X= ^{100%}⁄_{P%}

^{X}⁄_{Total value} = ^{P}⁄_{100}

X = ^{(P x Total value)}⁄_{100}

Example: Find out 20% of 80

We have:

^{80}⁄_{X} = ^{100%}⁄_{20%}

^{X}⁄_{80} = ^{20}⁄_{100}

X = ^{(20 x 80)}⁄_{100}

X = ^{1600}⁄_{100}

X = 16
