Answer to Problem 42CCR

  $\text{82\%}$ of $45$ is $\underset{\_}{36.9}$ .

Explanation of Solution

Given information :

Consider the given information:

  $\text{82\%}$ of $45$ is a number.

Formula used:

The Percent equation:

a is p percent of b can be written as:

  $a=p\%\cdot b$

Calculation :

As per problem,

  $\begin{array}{l}a=p\%\cdot b\text{ [Write percent equation]}\\ a=82\%\cdot 45\text{ [Substitute 82 for }p\text{ and 45 for }b]\\ a=0.82\cdot 45\text{ [Write percent as a decimal]}\\ a=36.9\text{ [Simplify]}\end{array}$

Therefore, $\text{82\%}$ of $45$ is $\underset{\_}{36.9}$ .
