Answer to Problem 1E

In the statement- $32\text{ is }40\%\text{ of }80$ , the percent is $40\%$ , the base is $80$ and the part of the base is $32$ .

Explanation of Solution

Given information: The provided statement is $32\text{ is }40\%\text{ of }80$ .

The percent equation is used to represent the percent, the base and the part of the base. The percent equation is $a=p\%·b$ where $a$ a part of the base is $b$ and $p\%$ is the percent.

In this question,

  $\begin{array}{l}a=p\%·b\text{ [The percent equation}\text{.]}\\ 32=40\%·80\text{ [Substitute 32 for }a,40\%\text{ for }p\%\text{ and 80 for }b.]\end{array}$

Hence, in the statement- $32\text{ is }40\%\text{ of }80$ , the percent is $40\%$ , the base is $80$ and the part of the base is $32$ .
