Exercise 22 Page 239

Fractions, decimals, and percents are three ways to show parts of a whole. We want to write a fraction as a decimal and as a percent. Let's do these things one at a time.

Decimal

To write a fraction as a decimal, we divide the numerator by the denominator.

We found that 34 expressed as a decimal is 0.75.

Percent

To write a fraction as a percent, we can use the equivalent decimal. To write a decimal as a percent, we multiply by 100 and add the percent symbol %.

We found that 0.75 expressed as a percent is 75 %.
