Interactions with Fractions

This math factoid, compliments of Learn Fun Facts, is just too good not to share… $\displaystyle \frac{18\,534}{9\,267} \times \frac{17\,469}{5\,823} = \frac{34\,182}{5\,697}$

Ah, but maybe you missed it. Did you notice that each digit 1-9 appears exactly once in all three fractions? Pretty cool. But I have to say that this is still my favorite fraction equation: $\displaystyle \frac{1}{2} + \frac{1}{3} + \frac{1}{6} = 1$

Simple. Beautiful.

On the other hand, I’m not sure I have a favorite fraction joke. I mean, how do you pick just one? The number of fraction jokes is a lot like $\displaystyle \lim_{x\to 0} \frac{1}{x}$.

That’s right. There’s no limit.
