Ответ:
- \(0,3\cdot1,6:0,84=\dfrac{0,3\cdot1,6}{0,84}=\dfrac{0,48}{0,84}=\dfrac{4}{7}\).
- \(6,3:(3,5\cdot2,7)=\dfrac{6,3}{3,5\cdot2,7}=\dfrac{6,3}{9,45}=\dfrac{2}{3}\).
- \(0,05:8,1\cdot45=\dfrac{0,05\cdot45}{8,1}=\dfrac{2,25}{8,1}=\dfrac{5}{18}\).
- \(0,15\cdot2,4:1,08=\dfrac{0,15\cdot2,4}{1,08}=\dfrac{0,36}{1,08}=\dfrac{1}{3}\).
- \(0,48:(0,044\cdot6)=\dfrac{0,48}{0,044\cdot6}=\dfrac{0,48}{0,264}=\dfrac{20}{11}\).
- \((8\cdot0,39):(5,2\cdot9)=\dfrac{8\cdot0,39}{5,2\cdot9}=\dfrac{3,12}{46,8}=\dfrac{1}{15}\).
Ответ: а) \(\dfrac{4}{7}\); б) \(\dfrac{2}{3}\); в) \(\dfrac{5}{18}\); г) \(\dfrac{1}{3}\); д) \(\dfrac{20}{11}\); е) \(\dfrac{1}{15}\).
