Answer 1

We have the following:

We can calculate the answer by means of a proportion.

We know that 36 is 30%, how do we want to know the total, we must calculate 100%, as follows:

`\begin{gathered} 36\rightarrow30 \\ x\rightarrow100 \\ x=(100\cdot36)/(30) \\ x=120 \end{gathered}`

The total number of students in the choir is 120
