15y = 60

y = 4 bars

Answer 2

Gail should pack 4 protein bars if she packs 3 water bottles.

First, write out her original ratio; 20:15. Now, you have _:3. Find how to get from 15 to 3. 15 divided by what equals 3? 5. So, to get from 15 to 3, you have to divide by 5. Do the same to 20. 20 divided by 5 equals 4. So, your ratio is 4:3. Gail should pack 4 protein bars if she packs 3 water bottles.
