Question

In a class of 75 students, the number of girls is just half that of the

number of boys. How many girls are there in the class? How many
boys are there in the class?

Answer 1

25 girls and 50 boys

Explanation:

let x be the number of boys

let x/2 be the number of girls

x + x/2 = 75

3x/2 = 75

3x = 150

x = 50

there are 50 boys and 50/2 = 25 girls.

50 + 25 = 75
