Question

The ratio to girls to boys in a class is 2:3 what is the number of girls in a class of 45 students.

Answer 1

Let the number of boys be 3a

Number of girls = 2a

Total number of students = 45

=> 3a + 2a = 45

=> 5a = 45

=> a = 9

Number of girls = 2 × 9 = 18

Number of boys = 3 × 9 = 27

Answer 2

Heya !!!


Let number of girls be 2X and number of boys be 3X.


Total number be students = 45



number of girls + number of boys = 45


2X + 3X = 45


X = 45/5 = 9



Number of girls = 2X = 2 × 9 = 18
