**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.**
