I don't know if i have the right approach but here goes:
It says a,b,c and f are four non-zero numbers. Let's assume that a=1 b=2 c=3 f=4. Plug them in to each answer choice and you will get:
A) 1/4=2/3 NOT EQUIVALENT
B) 4/3=2/1 If you reduce 2/2 from each proportion, they are equivalent.
C) 3/1=4/2 If you reduce 1/1 from each proportion, they are equivalent.
D) 1/3=2/4 If you reduce 1/1 from each proportion, they are equivalent.
E) 1x4/2x3=1/1>>4/6 ***, not equivalent?
Uhh, I just realized I made a mistake somewhere. I'm also puzzled XD
