196. Выполните действия:
1) $$8 + \frac{15}{22} = \frac{8 \cdot 22}{22} + \frac{15}{22} = \frac{176}{22} + \frac{15}{22} = \frac{176 + 15}{22} = \frac{191}{22} = 8\frac{15}{22}$$

2) $$\frac{11}{35}+2=\frac{11}{35}+\frac{2\cdot 35}{35}=\frac{11}{35}+\frac{70}{35}=\frac{11+70}{35}=\frac{81}{35}=2\frac{11}{35}$$

3) $$5\frac{4}{24}+\frac{7}{24}=5\frac{4+7}{24}=5\frac{11}{24}$$

197. Вычислите:
1) $$8\frac{4}{5}+2=10\frac{4}{5}$$

2) $$4\frac{5}{9}+3\frac{7}{9}=7\frac{5+7}{9}=7\frac{12}{9}=7+1\frac{3}{9}=8\frac{3}{9}=8\frac{1}{3}$$

Ответ: 1) $$8\frac{15}{22}$$; 2) $$2\frac{11}{35}$$; 3) $$5\frac{11}{24}$$; 1) $$10\frac{4}{5}$$; 2) $$8\frac{1}{3}$$
