Apainter used 3/4 of a gallon of paint to cover 1/4 of a wall. how many gallons of paint will the painter use for the entire wall?

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
