Question

Kenny, Marcus, and Sean each ate 1/5 gallon of ice cream from a

I-gallon tub. When they were done, how much ice cream was left?

If they wanted to eat 3/5gallon each, how much ice cream would
they need?

Answer 1

When they were done, there would be 2/5 of a gallon of ice cream left.

if they each wanted 3/5 of a gallon they would need 1 4/5 gallons of ice cream.

explanation: 1/5 X 3 = 3/5. 5/5 - 3/5 = 2/5

3/5 x 3 = 9/5 = 1 4/5
