1. Выполните действия: а) $$16 \frac{2}{17} + 14 \frac{7}{17} - 2 \frac{5}{17}$$; б) $$4 \frac{13}{29} + 13 \frac{8}{29} - 12 \frac{25}{29}$$.

а) $$16 \frac{2}{17} + 14 \frac{7}{17} - 2 \frac{5}{17} = (16 + 14 - 2) + (\frac{2}{17} + \frac{7}{17} - \frac{5}{17}) = 28 + \frac{4}{17} = 28 \frac{4}{17}$$. б) $$4 \frac{13}{29} + 13 \frac{8}{29} - 12 \frac{25}{29} = (4 + 13 - 12) + (\frac{13}{29} + \frac{8}{29} - \frac{25}{29}) = 5 + \frac{-4}{29} = 5 - \frac{4}{29} = 4 + \frac{29}{29} - \frac{4}{29} = 4 \frac{25}{29}$$. **Ответ:** а) $$28 \frac{4}{17}$$; б) $$4 \frac{25}{29}$$
