If a/b = 2, b/c = 3/2, c/d = 1/3, d/e = 2 and e/f = 2/3, then what is the value of abc/def ? Select
A) 27/14 B) 7/8 C) 4/9 D) 3/4 E) 9/4
Say a = 1. Then:   a/b = 2 --&gt; b = 1/2;   b/c = 3/2 --&gt; c = 1/3;   c/d = 1/3 --&gt; d = 1;   d/e = 2 --&gt; e = 1/2;   e/f = 2/3 --&gt; f = 3/4.   abc/def = (1*1/2*1/3)/(1*1/2*3/4) = 4/9.   Answer: 4/9.
