Question

If there is 30 students in a class and 18 are girls, what is the ratio of boys to total number of students in the class in decimal form?

Answer 1

Jadeli, this is the solution to the problem:

• Number of students in a class = 30

,

• Number of girls in the class = 18

,

• Number of boys in the class = 12 (30 - 18)

Ratio of boys to total number of students = 12/30 = 0.4 (decimal form).
