Question

There are 20 girls and 15 boys in a class.

What is the ratio of girls to that total number of students in the class?

Answer 1

Given, number of girls = 20

Number of boys = 15

Total number of students = Girls + Boys = 15 + 20 = 35

The ratio of number of girls to total students

= $\frac{Numberofgirls}{Totalnumberofstudents}$

= $\frac{20}{20+15}=\frac{20}{35}=\frac{4}{7}=4:7$
