Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Amount of paint needed to paint 3/4 of a room = 2/5 of a gallon

2. They can paint, on average how many rooms per gallon?

Let's use the Rule of Three Simple to answer this question, this way:

Paint                 Rooms

2/5 gallon          3/4

1 gallon               x

x = Number of rooms on average painted with one gallon of paint

x * 2/5 = 3/4 * 1

x = 3/4 / 2/5

x = 3/4 * 5/2 = 15/8 = 1 7/8

West Painting can paint, on average, 1 7/8 rooms per gallon of paint
