If 2a = 3b and ab ≠0, what is the ratio of a/3 to b/2?
Answers:
A) 27/8
B) 8/27
C) 1
D) 9/4
E) 81/64
A nice fast approach is the first find a pair of numbers that satisfy the given equation: 2a = 3b   Here's one pair: a =3 and b =2   What is the ratio of a/3 to b/3?   In other words, what is the value of (a/3)/(b/2)?   Plug in values to get: (a/3)/(b/2) = (3/3)/(2/2)=
