Starting with the process e+e-→DD¯, a new reconstruction method is employed to select events that contain candidates for both D→{\=K}e+νe and D¯→Ke-ν¯e decays. The branching fractions reported in this work are consistent within uncertainties with previous BESIII measurements that selected events containing D→{\=K}e+νe and hadronic D¯ decays. Combining our results with the lifetimes of the D0 and D+ mesons and the previous BESIII measurements leads to a ratio of the two decay partial widths of Γ¯D0→K-e+νeΓ¯D+→{\=K}0e+νe=1.039±0.021. This ratio supports isospin symmetry in the D0→K-e+νe and D+→{\=K}0e+νe decays within 1.9σ.",
