Ответ:

  1. \(2,4:1,44=240:144=\frac{5}{3}\).
  2. \(4,25:2,5=425:250=1,7\).
  3. \(0,03:0,0008=300:8=37,5\).
  4. \(\frac{3}{7}:\frac{9}{14}=\frac{3}{7}\cdot\frac{14}{9}=\frac{2}{3}\).
  5. \(8:\frac{3}{4}=8\cdot\frac{4}{3}=\frac{32}{3}=10\frac{2}{3}\).
  6. \(2:\frac{11}{3}=2\cdot\frac{3}{11}=\frac{6}{11}\).

Ответ: 1) \(\frac{5}{3}\); 2) 1,7; 3) 37,5; 4) \(\frac{2}{3}\); 5) \(10\frac{2}{3}\); 6) \(\frac{6}{11}\).
