Выполним действия:

1. $$3+\frac{5}{8} = 3\frac{5}{8}$$

   Ответ: $$3\frac{5}{8}$$

2. $$6\frac{8}{11}-4\frac{2}{11} = (6-4)+\frac{8-2}{11}=2+\frac{6}{11}=2\frac{6}{11}$$

   Ответ: $$2\frac{6}{11}$$

3. $$\frac{7}{12}+\frac{4}{12} = \frac{7+4}{12}=\frac{11}{12}$$

   Ответ: $$\frac{11}{12}$$

4. $$2\frac{5}{14}+1\frac{9}{14} = (2+1)+\frac{5+9}{14}=3+\frac{14}{14}=3+1=4$$

   Ответ: $$4$$

5. $$1\frac{1}{6}+\frac{5}{6} = 1+\frac{1+5}{6}=1+\frac{6}{6}=1+1=2$$

   Ответ: $$2$$

6. $$5\frac{6}{7}+3\frac{4}{7} = (5+3)+\frac{6+4}{7}=8+\frac{10}{7}=8+1\frac{3}{7}=9\frac{3}{7}$$

   Ответ: $$9\frac{3}{7}$$

7. $$1-\frac{3}{10} = \frac{10}{10}-\frac{3}{10} = \frac{10-3}{10}=\frac{7}{10}$$

   Ответ: $$\frac{7}{10}$$

8. $$4\frac{1}{9}-1\frac{5}{9} = 3\frac{10}{9}-1\frac{5}{9} = (3-1)+\frac{10-5}{9}=2+\frac{5}{9}=2\frac{5}{9}$$

   Ответ: $$2\frac{5}{9}$$
