Anomalous Cancellation on 2-Digit Numbers/Examples/16 over 64

Example of Anomalous Cancellation on 2-Digit Numbers
The fraction $\dfrac {16} {64}$ exhibits the phenomenon of anomalous cancellation:


 * $\dfrac {16} {64} = \dfrac 1 4$

as can be seen by deleting the $6$ from both numerator and denominator.

This is part of a longer pattern:
 * $\dfrac 1 4 = \dfrac {16} {64} = \dfrac {166} {664} = \dfrac {1666} {6664} = \cdots$
