Exercise 14 Page 239

Fractions, decimals, and percents are three ways to show parts of a whole. We want to write a percent as a decimal. First, notice the line on top of 2 in the given expression. 39.2% Recall that this line represents a repeating pattern. 39.2%=39.222222... % Now, to write a percent as a decimal, we ignore the percent symbol and move the decimal point two places to the left.

We found that 39.2 % expressed as a decimal is 0.392. We can also use a model to represent this number.
