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.

5 out of 4 people have trouble with fractions.

I will express polynomials as partial fractions. I will compute the value of continued fractions. I will even find a least common denominator. But I draw the line between the numerator and denominator.

What is one-fifth of a foot?
A toe.

How many tents can fit in a campground?
Ten, because ten tents (tenths) make a whole!

Before you go, here’s a fun little fraction problem for you:

What is 1/2 of 2/3 of 3/4 of 4/5 of 500?
