Вычисли разность выражений из номера 334 (пункт а)

- №334 - а) $7 \frac{1}{4} - 1 \frac{1}{6} = \frac{29}{4} - \frac{7}{6} = \frac{29 \cdot 3 - 7 \cdot 2}{12} = \frac{87 - 14}{12} = \frac{73}{12} = 6 \frac{1}{12}$ - б) $11 \frac{3}{8} - 1 \frac{1}{12} = \frac{91}{8} - \frac{13}{12} = \frac{91 \cdot 3 - 13 \cdot 2}{24} = \frac{273 - 26}{24} = \frac{247}{24} = 10 \frac{7}{24}$ - в) $2 \frac{1}{3} - 1 \frac{1}{7} = \frac{7}{3} - \frac{8}{7} = \frac{7 \cdot 7 - 8 \cdot 3}{21} = \frac{49 - 24}{21} = \frac{25}{21} = 1 \frac{4}{21}$ - г) $2 \frac{2}{3} - \frac{2}{11} = \frac{8}{3} - \frac{2}{11} = \frac{8 \cdot 11 - 2 \cdot 3}{33} = \frac{88 - 6}{33} = \frac{82}{33} = 2 \frac{16}{33}$ - №335 - а) $5 \frac{1}{6} - 1 \frac{1}{15} = \frac{31}{6} - \frac{16}{15} = \frac{31 \cdot 5 - 16 \cdot 2}{30} = \frac{155 - 32}{30} = \frac{123}{30} = 4 \frac{1}{10}$ - б) $5 \frac{1}{9} - 1 \frac{1}{6} = \frac{46}{9} - \frac{7}{6} = \frac{46 \cdot 2 - 7 \cdot 3}{18} = \frac{92 - 21}{18} = \frac{71}{18} = 3 \frac{17}{18}$ - в) $7 \frac{3}{6} - 1 \frac{3}{10} = 7 \frac{1}{2} - 1 \frac{3}{10} = \frac{15}{2} - \frac{13}{10} = \frac{15 \cdot 5 - 13}{10} = \frac{75 - 13}{10} = \frac{62}{10} = 6 \frac{1}{5}$
