In a class of 240 pupils, 2/5 of them are boys and the rest are girls. a) what is the fraction of girls? b) how many boys are in the class

A. 3/5 of the class are girls.
B. 96 of the pupils are boys.

A. To find this answer you subtract 2 from 5 to get 3 (numerator or top of fraction) then use 5 as the denominator or bottom of the fraction.

B. To find this answer, you divide 240 by 5, to show how many pupils are in 1/5 of the class (48). Then multiply 48 by 2, to get the 2/5 of the pupils who are boys (96).

I hope this helps!
