Ответ:
- \(x=\frac{2}{7}:\frac{6}{7}=\frac{2}{7}\cdot\frac{7}{6}=\frac{1}{3}\).
- \(x=1:\frac{8}{11}=\frac{11}{8}=1\frac{3}{8}\).
- \(x=25:\frac{5}{6}=25\cdot\frac{6}{5}=30\).
- \(x=\frac{1}{4}:6=\frac{1}{24}\).
- Из \(x:\frac{8}{25}=\frac{5}{32}\) получаем \(x=\frac{5}{32}\cdot\frac{8}{25}=\frac{1}{20}\).
- \(\frac{20}{63}:x=\frac{4}{7}\), значит \(x=\frac{20}{63}:\frac{4}{7}=\frac{20}{63}\cdot\frac{7}{4}=\frac{5}{9}\).
Ответ: 1) \(x=\frac{1}{3}\); 2) \(x=\frac{11}{8}\); 3) \(x=30\); 4) \(x=\frac{1}{24}\); 5) \(x=\frac{1}{20}\); 6) \(x=\frac{5}{9}\).
