Neil has 3 partially full cans of white paint. They cantain 1/3 gallon, 1/5 gallon, and 1/2 gallon of paint. About how much pain

Marianna [84]

Answer:

1 1/30 gallons, or 31/30 gallons of paint

Step-by-step explanation:

Before these fractions can be added together they have to have a common denominator. The Least Common Multiple of 2, 3, and 5 is 30, so

1/3 = 10/30 1/5 = 6/30 1/2 = 15/30

10/30 + 6/30 + 15/30 = 31/30, or 1 1/30
