Ответ:
- \(\square=\frac{5}{6}-\frac{1}{2}=\frac{5}{6}-\frac{3}{6}=\frac{1}{3}\).
- \(\square=\frac{7}{8}-\frac{3}{8}=\frac{4}{8}=\frac{1}{2}\).
- \(\square=\frac{9}{10}-\frac{2}{5}=\frac{9}{10}-\frac{4}{10}=\frac{1}{2}\).
- \(\square=\frac{11}{12}-\frac{1}{4}=\frac{11}{12}-\frac{3}{12}=\frac{8}{12}=\frac{2}{3}\).
- \(\square=1-\frac{1}{3}=\frac{2}{3}\).
