Answer 1

Answer:

Using the ratio and proportion method, we find that on an average 1.875 rooms can be painted per gallon.

Step-by-step explanation:

Concept: Use the method of ratio and proportion. Given that for 2/5 gallons of paint, we can paint 3/4 of rooms. So, for one gallon of paint, divide 2/5 by 3/4.

2/5 gallons of paint = 3/4 rooms

1 gallon of paint = $\frac{\frac{3}{4} }{\frac{2}{5} } = \frac{15}{8} =1.875$ rooms

So, on an average they can paint 1.875 rooms per gallon.
