Ответ:
- \(\frac{5}{6}\cdot\frac{3}{35}=\frac{1}{14}\).
- \(\frac{2}{9}:4=\frac{2}{9}\cdot\frac{1}{4}=\frac{1}{18}\).
- \(\frac{8}{35}:\frac{7}{9}=\frac{8}{35}\cdot\frac{9}{7}=\frac{72}{245}\).
- \(\frac{4}{9}\cdot18=8\).
- \(\frac{46}{75}\cdot\frac{23}{45}=\frac{1058}{3375}\).
Ответ: а) \(\frac{1}{14}\); б) \(\frac{1}{18}\); в) \(\frac{72}{245}\); г) 8; д) \(\frac{1058}{3375}\).
