Вычислите: 8 6/7 − 4 3/7 =; 11 − 6 2/5 =; 9 5/6 − 3 2/6 =; 7 2/8 − 3 5/8 =; 10 − 4 7/10 =.

1. \(8\frac{6}{7}-4\frac{3}{7}=4\frac{3}{7}\).
2. \(11-6\frac{2}{5}=10\frac{5}{5}-6\frac{2}{5}=4\frac{3}{5}\).
3. \(9\frac{5}{6}-3\frac{2}{6}=6\frac{3}{6}=6\frac{1}{2}\).
4. \(7\frac{2}{8}-3\frac{5}{8}=6\frac{10}{8}-3\frac{5}{8}=3\frac{5}{8}\).
5. \(10-4\frac{7}{10}=9\frac{10}{10}-4\frac{7}{10}=5\frac{3}{10}\).

Ответ: 4 3/7; 4 3/5; 6 1/2; 3 5/8; 5 3/10.
