# Anomalous Cancellation in Fractions

Did you know that you can just cancel out any common 3s, 6s, or 9s in the denominator and numerator of a fraction and leave it unchanged?

For example, 26 / 65 does equal 2 / 5. (Get rid of the sixes.)

And 163 / 326 does equal 1 / 2. (Get rid of the threes and the sixes.)

Does this seem too good to be true? We explain all in this video! (Watch till the end before becoming aghast!)
