Algebra word problem

Question

In Kool Kindergarten, children work in pairs. Each pair will share 12 crayons. If 216 crayons are being used, how many children are in class?

Answer 1

there are 216 crayons, therefore you need to divide these into 12 to be used by each pair of kids.

that means 216 divide by 12 is equal to 18.

but remember that is 18 pairs of kids, so the kids are actually 18 X 2 = 36 kids altogether.
