2. Вычислите: \((\frac{154-56}{36}:\frac{49}{6})\cdot \frac{6}{7}\)

1) \(\frac{154-56}{36}=\frac{98}{36}=\frac{49}{18}\)

2) \(\frac{49}{18}:\frac{49}{6}=\frac{49}{18} \cdot \frac{6}{49}=\frac{6}{18}=\frac{1}{3}\)

3) \(\frac{1}{3} \cdot \frac{6}{7}=\frac{6}{21}=\frac{2}{7}\)

Ответ: \(\frac{2}{7}\)
