$\frac{11}{15} : \frac{3}{8} = \frac{11}{15} * \frac{8}{3} = \frac{88}{45} = 1\frac{43}{45}$
$\frac{6}{35} : \frac{18}{25} = \frac{6}{35} * \frac{25}{18} = \frac{1}{7} * \frac{5}{3} = \frac{5}{21}$
$\frac{12}{55} : \frac{48}{77} = \frac{12}{55} * \frac{77}{48} = \frac{1}{5} * \frac{7}{4} = \frac{7}{20}$
$\frac{21}{40} : \frac{3}{4} = \frac{21}{40} * \frac{4}{3} = \frac{7}{10} * \frac{1}{1} = \frac{7}{10}$
$\frac{27}{50} : \frac{9}{25} = \frac{27}{50} * \frac{25}{9} = \frac{3}{2} * \frac{1}{1} = 1\frac{1}{2}$
$\frac{63}{64} : \frac{45}{56} = \frac{63}{64} * \frac{56}{45} = \frac{7}{8} * \frac{7}{5} = \frac{49}{40} = 1\frac{9}{40}$
$\frac{5}{8} : \frac{5}{32} = \frac{5}{8} * \frac{32}{5} = \frac{1}{1} * \frac{4}{1} = 4$
$\frac{14}{55} : \frac{1}{5} = \frac{14}{55} * \frac{5}{1} = \frac{14}{11} * \frac{1}{1} = 1\frac{3}{11}$
