Exercise 16 Page 237

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 a pattern in the given quotient! 17÷ 15 = 1.1333... We can write this repeating pattern as 1.13. 17÷ 15 = 1.13 We found that 1715 expressed as a decimal is 1.13.

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 1.13 expressed as a percent is 113.3 %.
