One Quarter as Pandigital Fraction

Theorem
There are $4$ ways $\dfrac 1 4$ can be made using all $9$ of the digits from $1$ to $9$:


 * $\dfrac 1 4 = \dfrac {3942} {15768}$


 * $\dfrac 1 4 = \dfrac {4392} {17568}$


 * $\dfrac 1 4 = \dfrac {5796} {23184}$


 * $\dfrac 1 4 = \dfrac {7956} {31824}$

Proof
Can be verified by brute force.
