Question

15/9 equals 40 over n

Answer 1

Given the following equation:

$\begin{gathered} \frac{15}{9}=\frac{40}{n} \\ \\ \end{gathered}$

You need to solve for the variable "n" in order to find its value.

The steps are shown below:

1. You can multiply both sides of the equation by "n":

$\begin{gathered} (n)(\frac{15}{9})=(\frac{40}{n})(n) \\ \\ \frac{15n}{9}=40 \end{gathered}$

2. Now you need to multiply both sides of the equation by 9:

$\begin{gathered} (9)(\frac{15n}{9})=(40)(9) \\ \\ 15n=360 \end{gathered}$

3. Finally, you can divide both sides of the equation by 15:

$\begin{gathered} \frac{15n}{15}=\frac{360}{15} \\ \\ n=24 \end{gathered}$

The answer is:

$n=24$
