Ответ:
- \(0{,}6=\frac{3}{5}\). Тогда \(\frac{3}{5}+\frac{1}{9}=\frac{27}{45}+\frac{5}{45}=\frac{32}{45}\).
- \(0{,}35=\frac{35}{100}=\frac{7}{20}\). Тогда \(\frac{11}{20}-\frac{7}{20}=\frac{1}{5}\).
- \(0{,}72=\frac{72}{100}=\frac{18}{25}\). Тогда \(\frac{18}{25}-\frac{5}{18}=\frac{324}{450}-\frac{125}{450}=\frac{199}{450}\).
- \(0{,}125=\frac{125}{1000}=\frac{1}{8}\). Тогда \(\frac{7}{24}-\frac{1}{8}=\frac{7}{24}-\frac{3}{24}=\frac{1}{6}\).
