We report determination of branching fractions for the decays {psi}(2S){yields}h+J/{psi}, where h=any, {pi}{sup +}{pi}{sup -}, {pi}{sup 0}{pi}{sup 0}, {eta}, {pi}{sup 0}, and {gamma}{gamma} through {chi}{sub c0,1,2}. These measurements use 27M {psi}(2S) decays produced in e{sup +}e{sup -} collision data collected with the CLEO detector. The resulting branching fractions and ratios thereof improve upon previously achieved precision in all cases, and in combination with other measurements permit determination of B({chi}{sub cJ}{yields}{gamma}J/{psi}) and B({psi}(2S){yields}light hadrons)
