105. Найдите значение выражения: а) $$(4\frac{3}{8} - 1\frac{2}{7} - 2\frac{5}{14}) \cdot 10\frac{1}{3};$$

Решим пример:

$$4\frac{3}{8} - 1\frac{2}{7} - 2\frac{5}{14} = 4\frac{21}{56} - 1\frac{16}{56} - 2\frac{20}{56} = 3\frac{77}{56} - 1\frac{16}{56} - 2\frac{20}{56} = 2\frac{61}{56} - 2\frac{20}{56} = \frac{61}{56} - \frac{20}{56} = \frac{41}{56};$$

$$10\frac{1}{3} = \frac{31}{3};$$

$$\frac{41}{56} \cdot \frac{31}{3} = \frac{1271}{168} = 7\frac{71}{168}$$.

Ответ: $$7\frac{71}{168}$$.
