Ответ:
- \(x=\frac{3}{5}:\frac{6}{5}=\frac{1}{2}\).
- \(x=1:\frac{4}{7}=\frac{7}{4}\).
- \(x=12:\frac{3}{4}=16\).
- \(x=\frac{2}{3}:3=\frac{2}{9}\).
- \(x=\frac{15}{28}\cdot\frac{7}{15}=\frac{1}{4}\).
- \(\frac{16}{27}:x=\frac{8}{9}\), поэтому \(x=\frac{16}{27}:\frac{8}{9}=\frac{2}{3}\).
Ответ: 1) \(\frac{1}{2}\); 2) \(\frac{7}{4}\); 3) \(16\); 4) \(\frac{2}{9}\); 5) \(\frac{1}{4}\); 6) \(\frac{2}{3}\).
