lubasha [3.4K]

Answer:

150

Step-by-step explanation:

We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other.

$\frac{24}{100}=\frac{36}{y}$

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

24y=100(36)

24y=3600

y=150.

There are 150 students in the choir.
