We present a measurement of the branching fractions of the Cabibbo favored B¯0→D+π- and the Cabibbo suppressed B¯0→D+K- decays. We find B(B¯0→D+π-)=(2.48±0.01±0.09±0.04)×10-3 and B(B¯0→D+K-)=(2.03±0.05±0.07±0.03)×10-4 decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the D+→K-π+π+ branching fraction. The ratio of branching fractions of B¯0→D+K- and B¯0→D+π- is measured to be RD=[8.19±0.20(stat)±0.23(syst)]×10-2. These measurements are performed using the full Belle dataset, which corresponds to 772×106BB¯ pairs and use the Belle II software framework for data analysis.
