Решим примеры:
- а) \(\frac{10}{11} - \frac{4}{11} + \frac{3}{11} = \frac{10 - 4 + 3}{11} = \frac{9}{11}\).
- б) \(4\frac{5}{9} + 3\frac{2}{9} = (4 + 3) + (\frac{5}{9} + \frac{2}{9}) = 7 + \frac{7}{9} = 7\frac{7}{9}\).
- в) 6 - \(2\frac{3}{8}\) = \(5\frac{8}{8} - 2\frac{3}{8} = (5 - 2) + (\frac{8}{8} - \frac{3}{8}) = 3 + \frac{5}{8} = 3\frac{5}{8}\).
- г) \(5\frac{6}{13} - 1\frac{11}{13} = 4\frac{19}{13} - 1\frac{11}{13} = (4 - 1) + (\frac{19}{13} - \frac{11}{13}) = 3 + \frac{8}{13} = 3\frac{8}{13}\).
Ответ: а) \(\frac{9}{11}\); б) \(7\frac{7}{9}\); в) \(3\frac{5}{8}\); г) \(3\frac{8}{13}\)
