Решим пример по действиям:
$$\frac{4}{15} + \frac{6}{35} : (2 - 1\frac{41}{49}) - \frac{1}{6}$$ = ?
1) $$2 - 1\frac{41}{49} = 2 - \frac{49+41}{49} = 2 - \frac{90}{49} = \frac{98 - 90}{49} = \frac{8}{49}$$
2) $$\frac{6}{35} : \frac{8}{49} = \frac{6}{35} * \frac{49}{8} = \frac{3}{5} * \frac{7}{4} = \frac{21}{20}$$
3) $$\frac{4}{15} + \frac{21}{20} = \frac{16}{60} + \frac{63}{60} = \frac{79}{60}$$
4) $$\frac{79}{60} - \frac{1}{6} = \frac{79}{60} - \frac{10}{60} = \frac{69}{60} = \frac{23}{20} = 1\frac{3}{20}$$
**Ответ: $$1\frac{3}{20}$$**
