If you would like to know how much did the bag of grapefruit weigh, you can calculate this using the following steps:
7 1/2 pounds - 1 5/8 pounds of apples - 2 3/16 pounds of bananas = 7 1/2 - 1 5/8 - 2 3/16 = 15/2 - 13/8 - 35/16 = 120/16 - 26/16 - 35/16 = 59/16 = 3 11/16 pounds of grapefruit
The correct result would be 3 11/16 pounds of grapefruit.
