As in making a fruit punch for a party, I mixed 1⁄2 gallon of grape juice with 3⁄4 gallon of orange juice, in order to know how many gallons of punch did I make we have to do the following calculation:
Grape juice: 1/2 = 0.5
Orange juice: 3/4 = 0.75
Total juice: grape juice + orange juice = 0.5 + 0.75
