$\frac{3}{7} : \frac{5}{6} = \frac{3}{7} * \frac{6}{5} = \frac{18}{35}$
$\frac{3}{14} : \frac{2}{21} = \frac{3}{14} * \frac{21}{2} = \frac{3}{2} * \frac{3}{2} = \frac{9}{4} = 2\frac{1}{4}$
$\frac{7}{16} : \frac{42}{43} = \frac{7}{16} * \frac{43}{42} = \frac{1}{16} * \frac{43}{6} = \frac{43}{96}$
$\frac{3}{4} : \frac{21}{40} = \frac{3}{4} * \frac{40}{21} = \frac{1}{1} * \frac{10}{7} = 1\frac{3}{7}$
$\frac{9}{25} : \frac{27}{50} = \frac{9}{25} * \frac{50}{27} = \frac{1}{1} * \frac{2}{3} = \frac{2}{3}$
$\frac{45}{56} : \frac{63}{64} = \frac{45}{56} * \frac{64}{63} = \frac{5}{7} * \frac{8}{7} = \frac{40}{49}$
$\frac{2}{3} : \frac{1}{6} = \frac{2}{3} * \frac{6}{1} = 2 * 2 = 4$
$\frac{65}{98} : \frac{26}{49} = \frac{65}{98} * \frac{49}{26} = \frac{65}{2} * \frac{1}{26} = \frac{65}{52} = 1\frac{13}{52}$
