Question

joan can paint 5 3/7 sections of a fence in 8 1/2 hours. if she continues to paint at this rate, how many more sections can she paint in one more hour

Answer 1

joan's rate = 5 3/7 / 8 1/2 = 38/7 * 2/17 = 76/119 = 0.64 sections per hour

joan can do 0.64 section if she keeps painting for one more hour
