Question

15/9 equals 40 over n

Answer 1

Given the following equation:

`\begin{gathered} (15)/(9)=(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)((15)/(9))=((40)/(n))(n) \\ \\ (15n)/(9)=40 \end{gathered}`

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

`\begin{gathered} (9)((15n)/(9))=(40)(9) \\ \\ 15n=360 \end{gathered}`

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

`\begin{gathered} (15n)/(15)=(360)/(15) \\ \\ n=24 \end{gathered}`

The answer is:

`n=24`
