Ответ:
- \(4\frac{14}{19}-2\frac{5}{19}=2\frac{9}{19}\).
- \(8\frac{7}{10}-5=3\frac{7}{10}\).
- \(12-\frac{7}{18}=11\frac{11}{18}\).
- \(11-3\frac{5}{12}=7\frac{7}{12}\).
- \(8\frac{7}{15}-3\frac{11}{15}=7\frac{22}{15}-3\frac{11}{15}=4\frac{11}{15}\).
- \(10\frac{9}{14}-3\frac{9}{14}=7\).
Ответ: а) \(2\frac{9}{19}\); б) \(3\frac{7}{10}\); в) \(11\frac{11}{18}\); г) \(7\frac{7}{12}\); д) \(4\frac{11}{15}\); е) \(7\).
