This paper describes new measurements from CLEO of the inclusive B→(formula presented) branching fractions. The inclusive branching fraction is B(B→(formula presented)X)=(12.11±0.39±0.88±1.38)% where the first error is statistical, the second is the systematic error, and the third is the error due to the uncertainty in the (formula presented) branching fraction. The branching fractions for the B→(formula presented) modes are found to be between 0.9% and 2.4% and are significantly more precise than previous measurements. The sum of the B→(formula presented) branching fractions is consistent with the results of fits to the inclusive (formula presented) momentum spectrum. Factorization is used to arrive at a value for (formula presented) decay constant.
