Question

In a class, a quarter of the students are boys. If there are 40 students in total, how many are girls?

Answer 1

Total number of students in class = 40

Number of boys = quarter of total number of students
= quarter of 40
= 40 $÷$ 4
= 10

Number of girls = total number of students - number of boys
= 40 - 10 = 30

So, the number of girls in the class = 30
