         When we say "Percent" we are really saying "per 100"

Picture

So 50% means 50 per 100
(50% of this box is green)

And 25% means 25 per 100
(25% of this box is green)

Examples

Picture
100% means all.

Example:

100% of 80 is 100/100 × 80 = 80

Picture
50% means half.

Example:

50% of 80 is 50/100 × 80 = 40

Picture
5% means   5/100ths.

Example:

5% of 80 is 5/100 × 80 = 4

Picture
A Percent can also be expressed as a Decimal or a Fraction

 A Half can be written...   


As a percentage: 50%
As a decimal: 0.5
As a fraction: 1/2


Example: 15% of 200 apples were bad. How many apples were bad?

15% =  15/100
And  15/ 200 × 200  =  15*  200/100  = 15*2=   30 apples


ANS: 30 apples were bad
