             (b) What is the ratio of number of girls to the total number of students in the class?

Answers (1)

Given,

Number of boys = 15

Number of girls = 20 

Total number of students = 15 + 20 = 35.

the ratio of the number of girls to the total number of students in the class:

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