During recess, two out of every three kids were playing soccer. The rest played basketball. If sixty-three kids were at recess, then how many kids were playing basketball?

Answer 1

Two out of every three kids were playing soccer, so 2/3 of 63 kids were playing soccer, which is 42 kids.

This means that the rest, which is 63 - 42 = 21 kids, were playing basketball.

Therefore, 21 kids were playing basketball during recess.
