15% = 15100

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

### 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
