Составьте программу действий и вычислите: $(3\frac{5}{6} - \frac{2}{6}) + 4 = $

1. $(3\frac{5}{6} - \frac{2}{6}) + 4 = 3\frac{3}{6} + 4 = 3\frac{1}{2} + 4 = 7\frac{1}{2}$ **Ответ:** $7\frac{1}{2}$ 2. $2\frac{1}{7} + (\frac{4}{7} + 1\frac{2}{7}) = 2\frac{1}{7} + 1\frac{6}{7} = 3\frac{7}{7} = 4$ **Ответ:** $4$ 3. $6\frac{2}{5} - (1\frac{3}{5} - \frac{1}{5}) = 6\frac{2}{5} - 1\frac{2}{5} = 5$ **Ответ:** $5$ 4. $(3\frac{7}{8} + \frac{1}{8}) - 2\frac{5}{8} = 3\frac{8}{8} - 2\frac{5}{8} = 4 - 2\frac{5}{8} = 3\frac{8}{8} - 2\frac{5}{8} = 1\frac{3}{8}$ **Ответ:** $1\frac{3}{8}$ 5. $\frac{7}{9} + (1\frac{2}{9} - \frac{5}{9}) = \frac{7}{9} + (\frac{11}{9} - \frac{5}{9}) = \frac{7}{9} + \frac{6}{9} = \frac{13}{9} = 1\frac{4}{9}$ **Ответ:** $1\frac{4}{9}$ 6. $(4\frac{2}{5} + \frac{4}{5}) + 1\frac{4}{5} = 4\frac{6}{5} + 1\frac{4}{5} = 5\frac{1}{5} + 1\frac{4}{5} = 6\frac{5}{5} = 7$ **Ответ:** $7$ 7. $6\frac{1}{4} - (3\frac{2}{4} + 1\frac{1}{4}) = 6\frac{1}{4} - (4\frac{3}{4}) = 5\frac{5}{4} - 4\frac{3}{4} = 1\frac{2}{4} = 1\frac{1}{2}$ **Ответ:** $1\frac{1}{2}$ 8. $(5 - 2\frac{3}{8}) - \frac{7}{8} = (4\frac{8}{8} - 2\frac{3}{8}) - \frac{7}{8} = 2\frac{5}{8} - \frac{7}{8} = 1\frac{13}{8} - \frac{7}{8} = 1\frac{6}{8} = 1\frac{3}{4}$ **Ответ:** $1\frac{3}{4}$
