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
