A box contained some red, blue, and green markers. For every 3 red markers, there were 2 blue markers. For every 3 blue markers, there were 7 green markers. A) Find the ratio of red markers to blue markers to green markers. B) When 7 markers were removed from the box, 1/4 of the remaining markers were red markers. How many markers were left in the box?

  1. r:b = 3:2 = 9:6
    b:g = 3:7 = 6:14

    r:b:g = 9:6:14

    assuming none of the ones removed were red,
    1/4 (9x+6x+14x - 7) = 9x

    Hmmm. I get x = -1

    better double-check my math and the problem.
