Q1> a,b, and c are integers and a<b<c. S is the set of all
integers from a to b, inclusive. Q is the set of all integers from b to
c, inclusive. The median of Set S is (3/4)b. The median of set Q is
(7/8)c. If R is the set of all integers from a to c, inclusive, what
fraction of c is the median of set R?
