Question

40 children from an after-school clubwent to matinee. This is 25%of the children club. How many children are in the club.

Answer 1

Use proportions to figure out the amount of children in the club.

If 40 is 25%, use the following formula to find the total amount:


`(40)/(25) = (x)/(100)`

Use cross multiplication.

40 * 100 = 4000
25 * x = 25x
25x = 4000

Divide both sides by 25.

x = 160

There are 160 total children in the club.
