In this equation is a+b/b manipulated by a/b + b/b, then the b/b becomes 1?

don't do this -- i.e., don't post a message that says "please answer my question".
this is called "bumping" the thread; it brings the thread up to the most recent position in the folder.

the problem, of course -- besides the fact that "reminder posts" are obnoxious, rude, and unprofessional -- is that we answer the posts strictly in order from oldest to newest. therefore, if you post a message, with no content, that says "please answer this post", then you are moving the thread to the LAST place in the queue.

please be patient -- we will get to all of the threads. if you make posts like this one, you're just making yourself wait longer.

thanks.

also, from now on, please post threads in the correct folder. this folder is for GMAT PREP SOFTWARE problems only, so this question doesn't belong here.

--

in answer to the question itself, yes, a fraction always equals 1 if its numerator and denominator are the same.
