In a class 3/5 of the pupils are boys. If there are 24 girls, how many boys are there in the class ?​

36 boys

Step-by-step explanation:

let x be the number of pupils in the class , then

x + 24 = x ( multiply through by 5 to clear the fraction )

3x + 120 = 5x ( subtract 3x from both sides )

120 = 2x ( divide both sides by 2 )

60 = x

Then

number of boys = × 60 = 3 × 12 = 36
