**Решение:**
1. **(0,875 - 0,7) : (5$$\frac{2}{7}$$ - 3$$\frac{15}{28}$$)**
* 0,875 - 0,7 = 0,175
* $$5\frac{2}{7} - 3\frac{15}{28} = \frac{37}{7} - \frac{99}{28} = \frac{148}{28} - \frac{99}{28} = \frac{49}{28} = \frac{7}{4} = 1,75$$
* 0,175 : 1,75 = 0,1
2. **[($$\frac{1}{4}$$ - 0,1 : 2) * $$\frac{5}{13}$$ + 1 : ($$\frac{3}{4}$$ + $$\frac{1}{3}$$)] * $$\frac{3}{8}$$**
* 0,1 : 2 = 0,05 = $$\frac{1}{20}$$
* $$\frac{1}{4} - \frac{1}{20} = \frac{5}{20} - \frac{1}{20} = \frac{4}{20} = \frac{1}{5}$$
* $$\frac{1}{5} * \frac{5}{13} = \frac{1}{13}$$
* $$\frac{3}{4} + \frac{1}{3} = \frac{9}{12} + \frac{4}{12} = \frac{13}{12}$$
* 1 : $$\frac{13}{12} = \frac{12}{13}$$
* $$\frac{1}{13} + \frac{12}{13} = \frac{13}{13} = 1$$
* 1 * $$\frac{3}{8} = \frac{3}{8}$$
**Ответ:**
* 1) 0,1
* 2) $$\frac{3}{8}$$
