A new technique is applied to data collected at the psi(3770) resonance to derive charmed-D-meson branching fractions without relying on the measurement of D-production cross sections. Measurements are presented for three decay modes of the D/sup 0/ (K/sup -/..pi../sup +/, K/sup -/..pi../sup -/..pi../sup +/..pi../sup +/, and K/sup -/..pi../sup +/..pi../sup 0/) and four decay modes of the D/sup +/ (K/sup -/..pi../sup +/..pi../sup +/, K/sup -/..pi../sup +/..pi../sup +/..pi../sup 0/, K/sub S//sup 0/..pi../sup +/, and K/sub S//sup 0/..pi../sup +/..pi../sup 0/). The resulting branching fractions are significantly larger than previous measurements.
