We report a very preliminary result on the measurement of the ratio of branching ratios, for two decays D{sup 0} meson, R = (BR(D{sup 0}{yields}K{pi}{pi}{pi})/BR(D{sup 0}{yields}K{pi})), using data from the E791 experiment. We find R = 1.96{+-}0.0286 (stat){+-}0.06 (sys). This is in agreement with and of similar precision to the current PDG average value 1.97{+-}0.09.
