  1. 4:5....added = 9
         4/9 (1800) = 7200/9 = 800 (red)
         5/9 (1800) = 9000/9 = 1000 (green)
         there were (1000 - 800) = 200 less red ones then green ones.

    11. 7/4 = 21/r
          cross multiply
          (7)(r) = (4)(21)
          7r = 84
           r = 84/7
           r = 12....Rod has 12 stickers
