Ответ:
\(\frac{7}{8}-\frac{1}{4}=\frac{7}{8}-\frac{2}{8}=\frac{5}{8}\).
\(\frac{11}{8}:\frac{5}{8}=\frac{11}{8}\cdot\frac{8}{5}=\frac{11}{5}\).
Ответ: \(\frac{11}{5}\).
\(\frac{7}{8}-\frac{1}{4}=\frac{7}{8}-\frac{2}{8}=\frac{5}{8}\).
\(\frac{11}{8}:\frac{5}{8}=\frac{11}{8}\cdot\frac{8}{5}=\frac{11}{5}\).
