Using 232 fb^\ensuremath-1 of e+e^\ensuremath- collision data recorded by the BABAR experiment, we measure the rates of three-body Cabibbo-suppressed decays of the D0 meson relative to the Cabibbo-favored decay, D0\ensuremath→\phantom\rule0ex0exK^\ensuremath-\ensuremathπ+\ensuremathπ0. We find: \fracB(D0\ensuremath→\ensuremathπ^\ensuremath-\ensuremathπ+\ensuremathπ0)B(D0\ensuremath→K^\ensuremath-\ensuremathπ+\ensuremathπ0)=(10.59\ifmmode±\else\textpm\fi0.06\ifmmode±\else\textpm\fi0.13)\ifmmode×\else\texttimes\fi10^\ensuremath-2 and \fracB(D0\ensuremath→K^\ensuremath-K+\ensuremathπ0)B(D0\ensuremath→K^\ensuremath-\ensuremathπ+\ensuremathπ0)=(2.37\ifmmode±\else\textpm\fi0.03\ifmmode±\else\textpm\fi\phantom\rule0ex0ex0.04)\ifmmode×\else\texttimes\fi10^\ensuremath-2, where the errors are statistical and systematic, respectively. These measurements are significantly more precise than the current world average measurements.
