They are 3 gallons of milk in the refrigerator. one is 1/3 full, one is 1/5 full, and one is 1/2 full. how much milk is in the refrigerator?

One gallon and 1/30

add 1/3 + 1/5 + 1/2

find the common denominators. the common denominator is 30.

10/30 + 6/30 +  15/30. add and you get 31/30. which equals one gallon and 1/30
