Answer:
They can make 720 quarts in 36 hours.
Explanation:
First we set up a ratio of 100 quarts:5 hours since that is a given ratio. Since hours was in the denominator of the ratio before, we place the 36 in the denominator of the other ratio, x quarts: 36 hours.
Setting them equal gives the following proportion:
100/5=x/36
Cross multiply to solve:
5x=3600
x=720
