Задание 5. Выполни действия со смешанными числами.

1. 2\(\frac{5}{13}\) + 5\(\frac{8}{13}\) = 7\(\frac{13}{13}\) = 8
2. 9\(\frac{15}{21}\) - 3\(\frac{10}{21}\) = 6\(\frac{5}{21}\)
3. 10\(\frac{16}{34}\) - 1\(\frac{14}{34}\) = 9\(\frac{2}{34}\) = 9\(\frac{1}{17}\)
4. 4\(\frac{7}{15}\) + 9\(\frac{13}{15}\) = 13\(\frac{20}{15}\) = 14\(\frac{5}{15}\) = 14\(\frac{1}{3}\)
5. 15\(\frac{1}{10}\) - 6\(\frac{4}{10}\) = 14\(\frac{11}{10}\) - 6\(\frac{4}{10}\) = 8\(\frac{7}{10}\)
6. 3\(\frac{6}{17}\) - 2\(\frac{7}{17}\) = 2\(\frac{23}{17}\) - 2\(\frac{7}{17}\) = \(\frac{16}{17}\)
7. 23\(\frac{6}{19}\) - 15\(\frac{16}{19}\) = 22\(\frac{25}{19}\) - 15\(\frac{16}{19}\) = 7\(\frac{9}{19}\)
8. 17\(\frac{6}{17}\) - 15\(\frac{9}{17}\) = 16\(\frac{23}{17}\) - 15\(\frac{9}{17}\) = 1\(\frac{14}{17}\)
9. 5\(\frac{9}{23}\) - 4\(\frac{15}{23}\) = 4\(\frac{32}{23}\) - 4\(\frac{15}{23}\) = \(\frac{17}{23}\)
10. 10\(\frac{1}{9}\) - 3\(\frac{5}{9}\) = 9\(\frac{10}{9}\) - 3\(\frac{5}{9}\) = 6\(\frac{5}{9}\)
11. 12\(\frac{8}{10}\) - 10\(\frac{9}{10}\) = 11\(\frac{18}{10}\) - 10\(\frac{9}{10}\) = 1\(\frac{9}{10}\)
12. 5\(\frac{2}{7}\) - 4\(\frac{5}{7}\) = 4\(\frac{9}{7}\) - 4\(\frac{5}{7}\) = \(\frac{4}{7}\)
13. 2\(\frac{3}{5}\) + 3\(\frac{4}{5}\) = 5\(\frac{7}{5}\) = 6\(\frac{2}{5}\)
14. 11\(\frac{6}{7}\) + 13\(\frac{5}{7}\) = 24\(\frac{11}{7}\) = 25\(\frac{4}{7}\)
15. 10\(\frac{5}{9}\) - 4\(\frac{5}{9}\) = 6
