Question

Divya is painting a room. She uses 3/4 gallon of paint to cover 1/5 of a wall. If the walls are all the same size, how much paint will she need to cover one wall?

Answer 1

3.75 gallons of paint would be needed to cover the wall.

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.
