dividing fractions is as easy as multiplying- basically because it almost IS multiplying.

My math teacher said something to help remember the process and I have never forgotten it: (yours is not to reason why, just invert and multiply) It's catchy!!

when something is the same numerator/denominator, it becomes a "1", because a fraction is really a division problem. so 20 goes into 20 once, which makes it one.

What's next? Are going to see postings about multiplication table? I thought this site is for more sophisticated stuff...
