Ответ:
- а) \(12:60=\frac{1}{5}\); б) \(1.5:60=0.025=\frac{1}{40}\).
- а) \(\frac{3}{7}:1\frac{1}{14}=\frac{3}{7}:\frac{15}{14}=\frac{3}{7}\cdot\frac{14}{15}=\frac{2}{5}\); б) \(1.6:0.8=2\).
- а) \(1\frac{1}{2}:4\frac{1}{2}=\frac{3}{2}:\frac{9}{2}=\frac{1}{3}\); б) \(1.2:4.8=0.25=\frac{1}{4}\).
- а) \(8\frac{2}{3}:2\frac{1}{6}=\frac{26}{3}:\frac{13}{6}=4\); б) \(0.08:8=0.01=\frac{1}{100}\).
