quarts per container .....quarts / container.....2/9 = 0.22 qts per container
or
1 qt = 32 oz.......so 2 qts would be (2 * 32) = 64 oz
64/9 = 7.11 oz
both answers are correct....it just depends on if u want the answer in quarts or ounces...and both those answers are rounded because both happen to be repeating decimals
