Ответ:

1) \(4\frac{5}{6}-1\frac{1}{3}=3+\frac{5}{6}-\frac{2}{6}=3\frac{1}{2}\).

2) \(3\frac{7}{8}-2\frac{1}{4}=1+\frac{7}{8}-\frac{2}{8}=1\frac{5}{8}\).

3) \(5\frac{1}{12}-2\frac{5}{6}=4\frac{13}{12}-2\frac{10}{12}=2\frac{1}{4}\).

4) \(2\frac{13}{15}-1\frac{2}{3}=1+\frac{13}{15}-\frac{10}{15}=1\frac{1}{5}\).

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

6) \(4\frac{9}{10}-1\frac{3}{5}=3+\frac{9}{10}-\frac{6}{10}=3\frac{3}{10}\).

7) \(7\frac{1}{2}-2\frac{1}{4}=5+\frac{2}{4}-\frac{1}{4}=5\frac{1}{4}\).

8) \(3\frac{5}{8}-1\frac{7}{16}=3\frac{10}{16}-1\frac{7}{16}=2\frac{3}{16}\).

9) \(8\frac{3}{4}-2\frac{5}{6}=7\frac{9}{12}-2\frac{10}{12}=5\frac{11}{12}\).

10) \(5\frac{11}{12}-3\frac{1}{3}=5\frac{11}{12}-3\frac{4}{12}=2\frac{7}{12}\).

11) \(6\frac{5}{14}-2\frac{3}{7}=6\frac{5}{14}-2\frac{6}{14}=5\frac{19}{14}-2\frac{6}{14}=3\frac{13}{14}\).

12) В последнем примере на изображении стоит знак сложения: \(9\frac{1}{5}+4\frac{7}{10}=13\frac{2}{10}+\frac{7}{10}=13\frac{9}{10}\).
