    Use the binomial series

    If you haven't already realized it, binomial coefficients can be generalized to take fractional values. Namely

    [tex]\binom{p/q}{m}=\frac{\frac{p}{q}(\frac{p}{q}-1)...(\frac{p}{q}-m+1)}{m!}[/tex].

    And furthermore, note that

    [tex]\binom{p/q}{1}=\frac{p}{q}[/tex]
