As a percentage:

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

15% = 15100

And 15100× 200= 15×200100
= 15 × 2
= 30 apples

30 apples are bad


Example: if only 10 of the 200 apples are bad, what percent is that?

As a portion, 10200 = 0.05

As a percent it is: 10200 x 100 = 5%

5% of those apples are bad


*

Example: A Skateboard is reduced 25% in price in a sale. The old price was $120. Find the new price.

First, uncover 25% of $120:

25% = 25100

And 25100× $120 = $30

25% of $120 is $30

So the reduction is $30

Take the reduction from the original price

$120 − $30 = $90

The Price of the Skateboard in the sale is $90
