Question

Edwin has 3 1/2
gallons of green paint. He uses 2/3
of the paint to paint his bedroom. He uses the rest of the paint for a mural in his garage. How much paint does Edwin use for the mural?
Write your answer as a whole number, fraction, or mixed number.

Answer 1

3 1/2 = 7/2.
Paint used = (2/3)·(7/2) = 7/3.
Remaining = 7/2 − 7/3 = (21−14)/6 = 7/6 = 1 1/6.

Edwin uses 1 1/6 gallons for the mural.
