# Four Fifths as Pandigital Fraction

## Theorem

The fraction $\dfrac 4 5$ can be expressed as a pandigital fraction in the following interesting way:

$\dfrac 4 5 = \dfrac {9876} {12 \, 345}$

## Proof

Can be found by brute force.

## Historical Note

According to David Wells in his $1986$ work Curious and Interesting Numbers, this result may have appeared in an article by Mitchell J. Friedman in Volume $8$ of Scripta Mathematica, but it is proving difficult to find an archived copy to consult directly.
