In a basketball freethrow 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 
Steve,
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
