# Percentages

Determine the percentage (%).

Complete the following statement. Write your answer as a decimal or whole number.

____ % of $8 =$2

The part is 2.

The whole is 8.

Let n represent the percent.

Write a proportion and find the cross products to solve for n.

 $\frac{2}{8}$ = $\frac{n}{100}$ 8n = 2 × 100 8n = 200 8n ÷ 8 = 200 ÷ 8 n = 25

25% of $8 is$2.

You could also find the answer by writing and solving an equation:

part = percentage of whole

2 =
 $\frac{n}{100}$ × 8

2 = $\frac{8n}{100}$

2 =
0.08
 n

 2 ÷ 0.08
=
0.08
 n
÷ 0.08

25 =
 n

25% of $8 is$2.

The % of 500 is 325
