Both faculty and student members of the Society of Women in Statistics at UCLA enjoy lunch in December 2018. Since the n-percentile of the gamma distribution is the x for which F(x;alpha,beta)=gamma(alpha,x * beta)/Gamma(alpha)=n, it follows that if you choose a different shape parameter, say k * beta, then the n-percentile of this new gamma distribution will be x / k.
