Measurements are presented of the branching fractions of the decays B0S → DsK and B0 → D-SK+ relative to the decays B0S → D-Sπ+ and B0 → Dπ+, respectively. The data used correspond to an integrated luminosity of 3.0 fb−1 of proton-proton collisions. The ratios of branching fractions are B(B0s → DsK) / B(B0s → Dsπ+) = 0.0752 ± 0.0015 ± 0.0019 and B(B0 → DsK+) / B(B0 → Dπ+) = 0.0129 ± 0.0005 ± 0.0008, where the uncertainties are statistical and systematic, respectively.
