5.355 Вычислите: 1) \(5\frac{4}{13} + \frac{6}{13}\); 2) \(\frac{9}{25} - \frac{6}{25} + \frac{2}{25}\); 4) \(9 \frac{5}{14} + 1 \frac{3}{14}\)

1) \(5\frac{4}{13} + \frac{6}{13} = 5 + \frac{4}{13} + \frac{6}{13} = 5 + \frac{10}{13} = 5\frac{10}{13}\) 2) \(\frac{9}{25} - \frac{6}{25} + \frac{2}{25} = \frac{9 - 6 + 2}{25} = \frac{5}{25} = \frac{1}{5}\) 4) \(9 \frac{5}{14} + 1 \frac{3}{14} = 9 + \frac{5}{14} + 1 + \frac{3}{14} = 10 + \frac{8}{14} = 10 + \frac{4}{7} = 10 \frac{4}{7}\)
