Answer: The ratio of protein bars to water bottles will be 4:3.
Explanation:
Since we have given that
Number of protein bars = 20
Number of water bottles = 15
We need to calculate the ratio of protein bars to water bottles which is given by
[tex]\text{ Number of protein bars}:\text{ Number of water bottles }\\\\=20:15\\\\=4:3[/tex]
So, the ratio of protein bars to water bottles will be 4:3.
