Question

A chemistry class is made up of ​% women and has women in it. What is the total number of students in the​ class?

Answer 1

67 students

Explanation:

Given

`\%Women = 55\%`

`Women = 37`

Required

The number of students

Let:

`n \to students`

So, we have:

`\%Women = (Women)/(n) * 100\%`

This gives:

`55\% = (37)/(n) * 100\%`

Make n the subject

`n = (37)/(55\%) * 100\%`

`n = (37)/(55) * 100`

`n = (3700)/(55)`

`n = 67.27273`

`n = 67` ---- Approximated
