Question

Allen and Ben are painting a fence. The ratio of the amount of work Allen does to the amount of work Ben does is 3:5. If the fence requires a total of 240 square feet to be painted, how many square feet does Ben paint?

Answer 1

150

Explanation:

Answer 2

The Ratio
allen : ben = 3:5
total of work in ratio = 3 + 5 = 8

Count the fence Ben paints
ben = ratio of ben/ total ratio × total of works
ben = 5/8 × 240
ben = 1,200/8
ben = 150

The fence Ben paints is 150 square feet
