5) \(\frac{1}{8} : \frac{3}{7} =\) \(\frac{1}{8} \cdot \frac{7}{3} = \frac{1 \cdot 7}{8 \cdot 3} = \frac{7}{24}\)

6) \(3 \frac{6}{7} : \frac{9}{28} =\) \(\frac{3 \cdot 7 + 6}{7} : \frac{9}{28} = \frac{27}{7} : \frac{9}{28} = \frac{27}{7} \cdot \frac{28}{9} = \frac{27 \cdot 28}{7 \cdot 9} = \frac{3 \cdot 4}{1 \cdot 1} = 12\)

7) \(\frac{5}{24} : 10 =\) \(\frac{5}{24} : \frac{10}{1} = \frac{5}{24} \cdot \frac{1}{10} = \frac{5 \cdot 1}{24 \cdot 10} = \frac{1}{24 \cdot 2} = \frac{1}{48}\)

8) \(5 : 7 \frac{1}{2} =\) \(5 : \frac{7 \cdot 2 + 1}{2} = 5 : \frac{15}{2} = \frac{5}{1} : \frac{15}{2} = \frac{5}{1} \cdot \frac{2}{15} = \frac{5 \cdot 2}{1 \cdot 15} = \frac{1 \cdot 2}{1 \cdot 3} = \frac{2}{3}\)
