Exercise 6 Page 135

To write a percent as a fraction, write the number part as a numerator over 100. To write a percent as a decimal, move the decimal point two places to the left and remove the percent symbol.

Example Fraction: 7/20
Decimal: 0.35

Practice makes perfect

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

Fraction

To write a percent as a fraction, we write the number part as a numerator over 100. 35 %=35/100Then, if possible, we simplify the fraction.
35/100
35÷ 5/100÷ 5
7/20
We found that 35 % expressed as a fraction is 35100, or 720.

Decimal

To write a percent as a decimal, we ignore the percent symbol and move the decimal point two places to the left.
percent as decimal: 0.38
We found that 35 % expressed as a decimal is 0.35.
