Ответ:
- \(\frac{2}{9}\cdot4=\frac{2\cdot4}{9}=\frac{8}{9}\).
- \(\frac{8}{60}\cdot5=\frac{40}{60}=\frac{2}{3}\).
- \(\frac{5}{24}\cdot3=\frac{15}{24}=\frac{5}{8}\).
- \(8\cdot\frac{3}{35}=\frac{24}{35}\).
- \(9\cdot\frac{7}{72}=\frac{63}{72}=\frac{7}{8}\).
- \(6\cdot\frac{5}{54}=\frac{30}{54}=\frac{5}{9}\).
