EXplanation:
To find the percent of 90 that is 13.5, we have:
Let the value be X.
X % of 90 = 13.5
[tex]\frac{X}{100}\ast90\text{ = 13.5}[/tex]Let's solve for X:
[tex]\begin{gathered} \text{Multiply both sides by 100:} \\ \frac{X}{100}\ast90\ast100\text{ = 13.5}\ast100 \\ \\ X\text{ }\ast\text{ 90 = }1350 \\ \end{gathered}[/tex][tex]\begin{gathered} \text{Divise both sides by 90:} \\ \frac{X\ast90}{90}=\frac{1350}{90} \\ \\ X\text{ = }15 \end{gathered}[/tex]Therefore 15 percent of 90 is 13.5
