Ответ:
- \(3+8\frac{5}{12}=11\frac{5}{12}\).
- \(10\frac{6}{7}-3=7\frac{6}{7}\).
- \(4\frac{2}{13}+5\frac{7}{13}=9\frac{9}{13}\).
- \(8\frac{7}{12}-4\frac{2}{12}=4\frac{5}{12}\).
- \(4\frac{8}{11}+5\frac{7}{11}=9\frac{15}{11}=10\frac{4}{11}\).
- \(7\frac{5}{9}-2\frac{8}{9}=6\frac{14}{9}-2\frac{8}{9}=4\frac{6}{9}=4\frac{2}{3}\).
- \(7-\frac{3}{8}=6\frac{8}{8}-\frac{3}{8}=6\frac{5}{8}\).
- \(10-3\frac{7}{15}=9\frac{15}{15}-3\frac{7}{15}=6\frac{8}{15}\).
