Ответ:
- \(\frac{4}{7}\cdot7:\frac{16}{23}=4\cdot\frac{23}{16}=\frac{23}{4}\).
- \(\frac{3}{5}\cdot5:\frac{6}{7}=3\cdot\frac{7}{6}=\frac{7}{2}\).
- \(\frac{4}{9}\cdot11:\frac{1}{11}=\frac{44}{9}\cdot11=\frac{484}{9}\).
- \(\frac{11}{15}\cdot2:\frac{10}{11}=\frac{22}{15}\cdot\frac{11}{10}=\frac{121}{75}\).
- \(\frac{15}{17}\cdot1:\frac{7}{17}=\frac{15}{17}\cdot\frac{17}{7}=\frac{15}{7}\).
- \(\frac{3}{13}\cdot4:\frac{5}{13}=\frac{12}{13}\cdot\frac{13}{5}=\frac{12}{5}\).
Ответ: а) \(\frac{23}{4}\); б) \(\frac{7}{2}\); в) \(\frac{484}{9}\); г) \(\frac{121}{75}\); д) \(\frac{15}{7}\); е) \(\frac{12}{5}\).
