Выполните действия: 1) 9 + 3/17; 2) 9/72 + 5... Вычислите: 1) 7 9/16 + 8 7/16...

### Задание 1. Выполните действия: 1) $9 + \frac{3}{17} = 9\frac{3}{17}$ 2) $\frac{9}{72} + 5 = 5\frac{9}{72} = 5\frac{1}{8}$ 3) $4\frac{5}{18} + 2\frac{4}{18} = (4 + 2) + \left(\frac{5}{18} + \frac{4}{18}\right) = 6 + \frac{9}{18} = 6\frac{1}{2}$ 4) $6\frac{7}{15} - 2\frac{3}{15} = (6 - 2) + \left(\frac{7}{15} - \frac{3}{15}\right) = 4 + \frac{4}{15} = 4\frac{4}{15}$ 5) $9\frac{11}{16} + 4\frac{3}{16} - 2\frac{2}{16} = (9 + 4 - 2) + \left(\frac{11}{16} + \frac{3}{16} - \frac{2}{16}\right) = 11 + \frac{12}{16} = 11\frac{3}{4}$ 6) $15\frac{7}{10} + 2\frac{2}{10} - 4\frac{1}{10} = (15 + 2 - 4) + \left(\frac{7}{10} + \frac{2}{10} - \frac{1}{10}\right) = 13 + \frac{8}{10} = 13\frac{4}{5}$ ### Задание 2. Вычислите: 1) $7\frac{9}{16} + 8\frac{7}{16} = (7 + 8) + \left(\frac{9}{16} + \frac{7}{16}\right) = 15 + \frac{16}{16} = 15 + 1 = 16$ 2) $4\frac{9}{19} + 5\frac{13}{19} = (4 + 5) + \left(\frac{9}{19} + \frac{13}{19}\right) = 9 + \frac{22}{19} = 9 + 1\frac{3}{19} = 10\frac{3}{19}$ 3) $1 - \frac{16}{25} = \frac{25}{25} - \frac{16}{25} = \frac{9}{25}$ 4) $4 - 1\frac{7}{12} = 3\frac{12}{12} - 1\frac{7}{12} = (3 - 1) + \left(\frac{12}{12} - \frac{7}{12}\right) = 2\frac{5}{12}$ 5) $6\frac{5}{14} - 2\frac{11}{14} = 5\frac{19}{14} - 2\frac{11}{14} = (5 - 2) + \left(\frac{19}{14} - \frac{11}{14}\right) = 3\frac{8}{14} = 3\frac{4}{7}$ 6) $19\frac{11}{35} - 12\frac{29}{35} = 18\frac{46}{35} - 12\frac{29}{35} = (18 - 12) + \left(\frac{46}{35} - \frac{29}{35}\right) = 6\frac{17}{35}$
