Ответ:
- \(2,4:1000=0,002\).
- \(3,6:18=0,2\).
- \(3:2=1,5\).
- \(0,7:2=0,35\).
- \(31:10=3,1\).
- \(3\cdot0,17=0,51\).
- \(0,04\cdot100=4\).
- \(4\frac{2}{5}+0,2=4,4+0,2=4,6\).
- \(-3,2\cdot\frac{3}{4}=-2,4\).
- \(6\frac{4}{7}-2,1=\frac{46}{7}-\frac{21}{10}=\frac{313}{70}=4\frac{33}{70}\).
- \(-0,3\cdot\left(-\frac{2}{5}\right)=0,12\).
- \(\frac{6}{25}-0,06=0,24-0,06=0,18\).
- \(3,5:\frac{3}{5}=3,5\cdot\frac{5}{3}=\frac{35}{6}=5\frac{5}{6}\).
- \(-2,5-3,045=-5,545\).
