Answer 1

Given:

In Ms. Perron’s class, 75% of the students are boys. There are 18 boys in the class.

We need to determine the total number of students in Ms. Perron's class.

Total number of students:

Let n denote the total number of students in Ms. Perron's class.

Thus, we have;

`(75)/(100)n=18`

Multiplying both sides of the equation by
`(100)/(75)`, we get;

`n=18* (100)/(75)`

Simplifying, we get;

`n=(1800)/(75)`

`n=24`

Therefore, the total number of students in Ms. Perron's class are 24.
