г) \(2\frac{1}{6} + 5\frac{1}{6} = (2+5) + (\frac{1}{6} + \frac{1}{6}) = 7 + \frac{2}{6} = 7\frac{1}{3}\) д) \(13\frac{2}{11} + 6\frac{7}{11} = (13+6) + (\frac{2}{11} + \frac{7}{11}) = 19 + \frac{9}{11} = 19\frac{9}{11}\) е) \(14\frac{9}{13} + 5\frac{3}{13} = (14+5) + (\frac{9}{13} + \frac{3}{13}) = 19 + \frac{12}{13} = 19\frac{12}{13}\)

2) Выполните вычитание.

г) \(13\frac{14}{19} - 4\frac{5}{19} = (13-4) + (\frac{14}{19} - \frac{5}{19}) = 9 + \frac{9}{19} = 9\frac{9}{19}\) d) \(25\frac{21}{67} - 16\frac{3}{67} = (25-16) + (\frac{21}{67} - \frac{3}{67}) = 9 + \frac{18}{67} = 9\frac{18}{67}\) е) \(14\frac{8}{15} - 3\frac{7}{15} = (14-3) + (\frac{8}{15} - \frac{7}{15}) = 11 + \frac{1}{15} = 11\frac{1}{15}\)
