Привет! Давай решим эти примеры на вычитание смешанных чисел. Будем приводить дроби к общему знаменателю. а) $11\frac{2}{3} - \frac{5}{6} = 11\frac{4}{6} - \frac{5}{6} = 10\frac{6+4}{6} - \frac{5}{6} = 10\frac{10}{6} - \frac{5}{6} = 10\frac{5}{6}$ б) $27\frac{9}{10} - 17\frac{4}{5} = 27\frac{9}{10} - 17\frac{8}{10} = (27-17) + (\frac{9}{10} - \frac{8}{10}) = 10\frac{1}{10}$ в) $8\frac{1}{25} - 2\frac{4}{5} = 8\frac{1}{25} - 2\frac{20}{25} = 7\frac{26}{25} - 2\frac{20}{25} = 5\frac{6}{25}$ г) $12\frac{1}{3} - 7\frac{3}{4} = 12\frac{4}{12} - 7\frac{9}{12} = 11\frac{16}{12} - 7\frac{9}{12} = 4\frac{7}{12}$ д) $1\frac{7}{18} - \frac{2}{9} = 1\frac{7}{18} - \frac{4}{18} = 1\frac{3}{18} = 1\frac{1}{6}$ е) $17\frac{9}{11} - 8\frac{2}{3} = 17\frac{27}{33} - 8\frac{22}{33} = 9\frac{5}{33}$ ж) $8\frac{5}{6} - 8\frac{7}{12} = 8\frac{10}{12} - 8\frac{7}{12} = \frac{3}{12} = \frac{1}{4}$ з) $11\frac{7}{32} - 10\frac{5}{8} = 11\frac{7}{32} - 10\frac{20}{32} = 10\frac{39}{32} - 10\frac{20}{32} = \frac{19}{32}$ и) $10\frac{1}{9} - 4\frac{16}{21} = 10\frac{7}{63} - 4\frac{48}{63} = 9\frac{70}{63} - 4\frac{48}{63} = 5\frac{22}{63}$ к) $4\frac{2}{81} - 3\frac{2}{27} = 4\frac{2}{81} - 3\frac{6}{81} = 3\frac{83}{81} - 3\frac{6}{81} = \frac{77}{81}$ л) $25\frac{3}{11} - 4\frac{5}{22} = 25\frac{6}{22} - 4\frac{5}{22} = 21\frac{1}{22}$
