If a/b = 6/5, Then (5a + 4b) / (5a - 4b) = ?  Choose one
A) 4
B) 7
C) 5
D) 3
E) 6
Answer   Dividing numerator as well as denominator by b, we get   Given Exp. = (5a + 4b) / (5a - 4b) = (5a/b + 4) / (5a/b - 4)   Since a/b = 6/5   this implies that   =[(5*6)/5 +4]/[(5*6)/5 -4)]   = (6 + 4) / (6 - 4)=
