Thanks for the answer. and sorry for the typo.
the question is why it is wrong to say a/c>b/c while a>b>0 and c>d>0?
what has d got to do with it ??/
if a,b,c are +ve and a>b>0 and c>0
Thanks for the explanation. That's why I thought too. I do not know why it said "it is wrong" in the Study Guide. When you have time, you can check out the Gmat Study Guide to see if it is accurate the way I read it.
Thanks a lot
