## Changing Decimals to Percents

To change a decimal to a percent, move the decimal point two places to the right and affix the % sign.

Math Note: If the decimal is located at the end of the number, do not write it.

#### Example 1

Write 0.78 as a percent.

0.78 = 78%

#### Example 2

Write 0.02 as a percent.

0.02 = 2%

#### Example 3

Write 1.29 as a percent.

1.29 = 129%

#### Example 4

Write 0.682 as a percent.

0.682 = 68.2%

#### Example 5

Write 0.0051 as a percent.

0.0051 = 0.51%

#### Example 6

Write 8 as a percent.

8 = 8.00 = 800%
