Answer:

67 students

Step-by-step explanation:

Given

[tex]\%Women = 55\%[/tex]

[tex]Women = 37[/tex]

Required

The number of students

Let:

[tex]n \to students[/tex]

So, we have:

[tex]\%Women = \frac{Women}{n} * 100\%[/tex]

This gives:

[tex]55\% = \frac{37}{n} * 100\%[/tex]

Make n the subject

[tex]n = \frac{37}{55\%} * 100\%[/tex]

[tex]n = \frac{37}{55} * 100[/tex]

[tex]n = \frac{3700}{55}[/tex]

[tex]n = 67.27273[/tex]

[tex]n = 67[/tex] ---- Approximated
