In a basketball free-throw shooting contest, the points made by Sam and Wilbur were in the ratio 7:9. Wilbur made 6 more points than Sam. find the number of points made by each.

  • Math - ,

    The ratio means that S/W = 7/9

    But you also have W = S + 6

    S/(S+6) = 7/9
    9S = 7(S+6)
    9S = 7S + 42
    2S = 42
    S = 21
    W = 27

    Note that 21/27 = 3*7/3*9 = 7/9
