N2 - By analyzing an e+e- data sample corresponding to an integrated luminosity of 2.93 fb-1 taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fractions of the Cabibbo-favored hadronic decays D0→K-π+η′, D0→KS0π0η′, and D+→KS0π+η′, which are determined to be (6.43±0.15stat±0.31syst)×10-3, (2.52±0.22stat±0.15syst)×10-3, and (1.90±0.17stat±0.13syst)×10-3, respectively. The precision of the branching fraction of D0→K-π+η′ is significantly improved, and the processes D0→KS0π0η′ and D+→KS0π+η′ are observed for the first time.
