Using a sample of 4.7 fb-1 integrated luminosity accumulated with the CLEO-II detector at the Cornell Electron Storage Ring (CESR), we have measured the ratios of the branching fractions B(τ-K-h+π-ντ)/B(τ-h-h+h-ντ)=(5.16±0.20±0.50)×10-2, B(τ-K-h+π-π0ντ)/B(τ-h-h+h-π0ντ)=(2.54±0.44±0.39)×10-2, B(τ-K-K+π-ντ)/B(τ-h-h+h-ντ)=(1.52±0.14±0.29)×10-2, and the upper limit B(τ-K-K+π-π0ντ)/B(τ-h-h+h-π0ντ)<0.0154 at 95% C.L. Coupled with additional experimental information, we use our results to extract information on the structure of three-prong tau decays to charged kaons.
