OK, OK, OK!? Wait a minute here!? How on earth did I know to multiply that guy by 125?!
Heh, heh...? Because I'm smart!? Alright, I'll tell you how I knew.
I know that I want that denominator to be 10 or 100 or 1000 or 10,000... a power of 10...? And 10's are made up of 2's and 5's:
So, we need a PAIR of 2's and 5's!
Look at this guy:
Here's another one:
Note that this will ONLY work if your denominator is made up of nothing but 2's and/or 5's.
Can you convert? this way?
But, there will be another way...? There will be another way.
