34. Вычислите \(\left(\frac{7}{16}+\frac{3}{8}\right)-\left(\frac{7}{8}-\frac{27}{32}\right)\).

\[\left(\frac{7}{16}+\frac{3}{8}\right)-\left(\frac{7}{8}-\frac{27}{32}\right)=\left(\frac{14}{32}+\frac{12}{32}\right)-\left(\frac{28}{32}-\frac{27}{32}\right)=\frac{26}{32}-\frac{1}{32}=\frac{25}{32}.\]

Ответ: \(\frac{25}{32}\).
