In mrs Wilsons class there are 24 boys and the girls are 2/5 the class ... How many girls are in mrs Wilson class

• 8thMath -

C = numbers of students in class

Boys = 3 / 5 of the class

( 3 / 5 ) C = 24 Multiply both sides by 5

3 C = 24 * 5

3 C = 120 Divide both sides by 3

C = 120 / 3 = 40

girls = ( 2 / 5 ) * 40 = 80 / 5 = 16
