One Half as Pandigital Fraction

Theorem
There are $12$ ways $\dfrac 1 2$ can be made using all $9$ of the digits from $1$ to $9$:


 * $\dfrac 1 2 = \dfrac {6729} {13 \, 458}$


 * $\dfrac 1 2 = \dfrac {6792} {13 \, 584}$


 * $\dfrac 1 2 = \dfrac {6927} {13 \, 854}$


 * $\dfrac 1 2 = \dfrac {7269} {14 \, 538}$


 * $\dfrac 1 2 = \dfrac {7293} {14 \, 586}$


 * $\dfrac 1 2 = \dfrac {7329} {14 \, 658}$


 * $\dfrac 1 2 = \dfrac {7692} {15 \, 384}$


 * $\dfrac 1 2 = \dfrac {7923} {15 \, 846}$


 * $\dfrac 1 2 = \dfrac {7932} {15 \, 864}$


 * $\dfrac 1 2 = \dfrac {9267} {18 \, 534}$


 * $\dfrac 1 2 = \dfrac {9273} {18 \, 546}$


 * $\dfrac 1 2 = \dfrac {9327} {18 \, 654}$

Proof
Can be verified by brute force.
