Answer to Problem 18MCQ

The number $\text{76 is 95\% of 80}\text{.}$

Explanation of Solution

Given information: What number is $95\%\text{ of 80}$ ?

Calculation: Percent $(\%)$ means ‘out of $100$ ’ and when dealing with percents the word ‘of’ means ‘times or to multiply’.

Hence, $95\%$ can be written as $\frac{95}{100}$ and $95\%\text{ of 80}$ can be written as $\frac{95}{100}\times 80$ .

Let, The number we are looking for is $x\text{.}$

Let’s find the value of $x$ ,

  $\begin{array}{l}x=\frac{95}{100}\times 80\\ x=\frac{95\times 4}{5}\\ x=19\times 4\\ x=76\end{array}$

Hence, The number $\text{76 is 95\% of 80}\text{.}$
