Ответ:
- \(9\frac{4}{5}-5=4\frac{4}{5}\); \(20\frac{19}{24}-\frac{6}{24}=20\frac{13}{24}\); \(34\frac{9}{17}-6\frac{2}{17}=28\frac{7}{17}\).
- \(3\frac{15}{27}-\frac{15}{27}=3\); \(7\frac{14}{15}-2\frac{3}{15}=5\frac{11}{15}\); \(15\frac{26}{33}-4\frac{5}{33}=11\frac{21}{33}=11\frac{7}{11}\).
- \(18\frac{10}{31}-9=9\frac{10}{31}\); \(12\frac{21}{28}-3\frac{9}{28}=9\frac{12}{28}=9\frac{3}{7}\); \(41\frac{9}{11}-18\frac{6}{11}=23\frac{3}{11}\).
