# If Orlando missed 5 out of 40 questions on the test, what percent of the questions did he get right?

Nov 1, 2016

color(green)(87.5%)

#### Explanation:

Orlando got $40 - 5 = 35$ out of $40$ right.

That is he got $\frac{35}{40}$ right.

As a percentage:
$\textcolor{w h i t e}{\text{XXX}} \frac{35}{40} = \frac{35}{\cancel{40}} _ 2 \times {\cancel{100}}^{5} / \textcolor{red}{100}$

$\textcolor{w h i t e}{\text{XXXXX}} = \frac{\frac{175}{2}}{\textcolor{red}{100}}$

$\textcolor{w h i t e}{\text{XXXXX}} = \frac{87.5}{\textcolor{red}{100}}$

color(white)("XXXXX")=87.5 "per 100"

color(white)("XXXXX")=87.5% (since "per cent" means "per humdred")
