Ответ:
- \(4-\frac25=3\frac35\).
- \(3+1-\frac25=3\frac35\).
- \(3+\frac52-\frac52=3\).
- \(3\frac58-3\frac35=\frac{25}{8}-\frac{18}{5}=\frac{125-144}{40}=-\frac{19}{40}\).
- \(2-\frac{11}{21}=1\frac{10}{21}\).
- \(6-\frac47=5\frac37\).
- \(8-\frac3{10}=7\frac7{10}\).
- \(11-\frac6{10}=10\frac4{10}=10\frac25\).
- \(5-\frac9{20}=4\frac{11}{20}\).
- \(10-\frac38=9\frac58\).
- \(1-\frac47=\frac37\).
- \(3-\frac7{13}=2\frac6{13}\).
- \(1-\frac35=\frac25\).
