Answer:
3.75 gallons of paint would be needed to cover the wall.
Step-by-step explanation:
She uses 3/4 gallon of paint to cover 1/5 of a wall.
how much paint will she need to cover one wall?
The straightforward way of solving this question is to simply add up the amount of paint for each one - fifth of the wall.
This means;
Total amount of paint = 3/4 + 3/4 + 3/4 + 3/4 + 3/4
Total amount of paint = (3 + 3 + 3 + 3 + 3 ) / 4 = 15/4 = 3.75 gallons
3.75 gallons of paint would be needed to cover the wall.
