Выполним действие $$(4 \frac{5}{12} - 3 \frac{13}{24}) : 1 \frac{3}{4} + \frac{7}{6}$$.
1) $$4 \frac{5}{12} - 3 \frac{13}{24} = 4 \frac{10}{24} - 3 \frac{13}{24} = 3 \frac{34}{24} - 3 \frac{13}{24} = \frac{21}{24} = \frac{7}{8}$$.
2) $$1 \frac{3}{4} = \frac{7}{4}$$.
3) $$\frac{7}{8} : \frac{7}{4} = \frac{7}{8} \cdot \frac{4}{7} = \frac{1}{2}$$.
4) $$\frac{1}{2} + \frac{7}{6} = \frac{3}{6} + \frac{7}{6} = \frac{10}{6} = \frac{5}{3} = 1 \frac{2}{3}$$.
Ответ: $$1 \frac{2}{3}$$
