Step-by-step explanation:

Answer 2

Find the rate at which you work, that is, the # of walls painted per hour:

13 1/3 walls          40/3

------------------  = ---------- wall per hour

14 1/4 hr              57/4

Keep 40/3 as it is; invert the divisor (57/4) and then multiply the result by 40/3:

40        4        160 wall

------ * ------  = --------------- = approx. 0.94 wall in one hour, or 160/171 wall / hr

  3       57        171 hr
