Allen and Ben are painting a fence. The ratio of the amount of work Allen does to the amount of work Ben does is 5:2. If the fence requires a total of 1400 square feet to be painted, how many square feet does Ben paint?

SO the ratio of Allen to Ben is 5:2. First, I would add them up. After that, I divided 1400/7 which equals 200. You have to multiply this by Ben's ratio which is 200*2 and that is 400 sq feet.
