5.355 Вычислите: 1) 5 4/13 + 6/13 2) 9/25 - 6/25 + 2/25 3) 5 2/7 - 4 1/7 + 3 4/7 4) 9 5/14 + 13/14

1) \(5 \frac{4}{13} + \frac{6}{13} = 5 \frac{4+6}{13} = 5 \frac{10}{13}\) 2) \(\frac{9}{25} - \frac{6}{25} + \frac{2}{25} = \frac{9-6+2}{25} = \frac{5}{25} = \frac{1}{5}\) 3) \(5 \frac{2}{7} - 4 \frac{1}{7} + 3 \frac{4}{7} = (5-4+3) + \frac{2-1+4}{7} = 4 + \frac{5}{7} = 4 \frac{5}{7}\) 4) \(9 \frac{5}{14} + \frac{13}{14} = 9 + \frac{5+13}{14} = 9 + \frac{18}{14} = 9 + 1 \frac{4}{14} = 10 \frac{2}{7}\)
