Question

What percent of 90 is 13.5? *

Answer 1

15%

Step-by-step explanation:

To find the percent of 90 that is 13.5, we have:

Let the value be X.

X % of 90 = 13.5

`(X)/(100)\ast90\text{ = 13.5}`

Let's solve for X:

`\begin{gathered} \text{Multiply both sides by 100:} \\ (X)/(100)\ast90\ast100\text{ = 13.5}\ast100 \\ \\ X\text{ }\ast\text{ 90 = }1350 \\ \end{gathered}`
`\begin{gathered} \text{Divise both sides by 90:} \\ (X\ast90)/(90)=(1350)/(90) \\ \\ X\text{ = }15 \end{gathered}`

Therefore 15 percent of 90 is 13.5
