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

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
