Y’all help me plz

Answer 1

A

Explanation:

So if 45 students represent 1/5 of the school, and x is the number of students in the school, then 45 will simply represent 1/5 of x.

This means that the equation is 1/5x = 45.

Now, you have to solve the equation.

`(1)/(5) x = 45`

Multiply both sides of the equation by 5

`(1)/(5)x * 5 = 45 * 5\\x = 225`

This means that there are 225 students.
