Question

a painter used 3/4 of a gallon of paint to cover 1/4 of the wall. How much paint does a painter need to cover a whole wall?

Answer 1

Explanation:

3 gallons because 3/4 of a gallon covers 1/4 of a wall so you multiply the amount of gallons used for a wall times 4 which is 12/4 (keep the denominator the same ) and then divide 12 by 4 which is 3 gallons
