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.
