Вопрос:

35. Вычислите: \(-\frac{29}{15}+\frac{14}{27}:\frac{4}{7}+2:3\frac{1}{7}\).

Ответ:

\[\frac{14}{27}:\frac{4}{7}=\frac{14}{27}\cdot\frac{7}{4}=\frac{49}{54}.\]

\[2:3\frac{1}{7}=2:\frac{22}{7}=\frac{7}{11}.\]

\[-\frac{29}{15}+\frac{49}{54}+\frac{7}{11}=\frac{-638+245+210}{330}=-\frac{183}{330}=-\frac{61}{110}.\]

Ответ: \(-\frac{61}{110}\).
