Question

Angela paints a wall that has an area of 42 2/3 square yards. She uses 1 1/3 gallons of paint. What is Angela's rate of paint coverage in square yards per gallon

Answer 1

Yards= 42  2/3 yd=42 + 2/3 yd=(42*3 + 2)/3 yd=128/3 yd
Gallons=1  1/3 Gallons=1+1/3 gallons=(3*1+1)/3 gallons=4/3 gallons.

Rate=number of yards / number of gallons.
Rate=(128/3 yd) / (4/3 gallons)=32 yd/gallon.

Answer: Angela´s rate=32 yards / gallons
