I attached a pic of a practice GRE problem.
The answer is D) relationship cannot be determined.
I understand this answer and it is actually what I picked, but my 2 methods of doing this problem is contradicting each other.
If you use the method of plugging in random #s you'll discover that the answer is D.
However, my other method is trying to match A&B.
For quantity A:
we get (w+z)/(wz)
For B:
(z+w)/(zw)=(w+z)/(zw) <<<<<Can I not do this flip for some reason? It is the only place where I can see a source of error
=(w+z)/(wz)
Divide both A&B by w+z and multiplying by wz we getL
A=1, B= 1
So this would mean that A>B, however this clearly contradicts my other answer and I can't identify why.
