Question

How many basketballs are in the locker, if there are 18 baseballs and basketballs in one gym storage locker and there are 3 baseballs for every 6 basketballs in the locker?

Answer 1

There are `12` basketballs.

The basketballs are twice of the baseballs.

So if there are `k` baseballs, there are `2k` basketballs.

Since `k+2k=18`, `k` is `6` so there are `6` baseballs and `12` basketballs.
