2. Выполните действия: 1) \(\frac{8}{29} + \frac{14}{29}\); 2) \(7\frac{5}{31} - 4\frac{2}{31} + 2\frac{11}{31}\); 4) \(7\frac{3}{7} - 2\frac{6}{7}\).

1) \(\frac{8}{29} + \frac{14}{29} = \frac{8+14}{29} = \frac{22}{29}\)

2) \(7\frac{5}{31} - 4\frac{2}{31} + 2\frac{11}{31} = (7 - 4 + 2) + (\frac{5}{31} - \frac{2}{31} + \frac{11}{31}) = 5 + \frac{5 - 2 + 11}{31} = 5 + \frac{14}{31} = 5\frac{14}{31}\)

4) \(7\frac{3}{7} - 2\frac{6}{7} = 7\frac{3}{7} - 2\frac{6}{7} = 6\frac{10}{7} - 2\frac{6}{7} = (6-2) + (\frac{10}{7} - \frac{6}{7}) = 4 + \frac{4}{7} = 4\frac{4}{7}\)

Ответ: 1) \(\frac{22}{29}\); 2) \(5\frac{14}{31}\); 4) \(4\frac{4}{7}\)
