By analyzing an e(+)e(-) annihilation data sample with an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the hadronic decays D-0 -> K- pi(+)omega, D-0 -> K-S(0)pi(0)omega and D+ -> K-S(0)pi(+)omega to be (3.392 +/- 0.044(stat) +/- 0.085(syst))%, (0.848 +/- 0.046(stat) +/- 0.031(syst))%, and (0.707 +/- 0.041(stat) +/- 0.029(syst))%, respectively. The accuracy of the branching fraction measurement of the decay D-0 -> K- pi(+)omega is improved by a factor of seven compared to the world average value. The D-0 -> K-S(0)pi(0)omega and D+ -> K-S(0)pi(+)omega decays are observed for the first time.
