Question

The ratio of girls to boys in Liza’s classroom is 5 to 4. How many girls are in her classroom if there is a total of 27 students?

Answer 1

Number of girls = 15

Explanation:

girls : boys = 5 : 4

Number of girls = 5x

Number of boys = 4x

Total students = 27

5x +4x = 27

9x = 27

x = 27/9

x = 3

Number of girls = 5x = 5*3 = 15
