Question

A school has 360 students. 4/9 of them are girls. 3/5 of them are girls below the age of ten. How many girls are in the school and how many are above the age of ten?

Answer 1

To find total number of girls multiply total students by the fraction of girls:

360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.

If 3/5 are below the age of ten, that means 2/5 are above the age of ten.

Multiply the total number of girls by 2/5:

160 x 2/5 = 320/5 = 64

There are 64 girls above the age of ten.
