Вопрос:

Вычислите: \(\left(\frac{5}{16}-1\frac{1}{8}\right)-\left(\frac{5}{6}+\frac{3}{14}\right)\).

Ответ:

\(\frac{5}{16}-\frac{9}{8}=\frac{5}{16}-\frac{18}{16}=-\frac{13}{16}\).

\(\frac{5}{6}+\frac{3}{14}=\frac{35}{42}+\frac{9}{42}=\frac{44}{42}=\frac{22}{21}\).

\(-\frac{13}{16}-\frac{22}{21}=-\frac{273+352}{336}=-\frac{625}{336}\).

Ответ: \(-\frac{625}{336}\).
