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: $$7\frac{71}{168}$$.
