Ответ:

$\frac{2}{15} :\frac{4}{25} = \frac{2*25}{15*4} = \frac{50}{60} = \frac{5}{6}$

$\frac{9}{34} :\frac{9}{10} = \frac{9*10}{34*9} = \frac{10}{34} = \frac{5}{17}$

$\frac{8}{21} :\frac{20}{28} = \frac{8*28}{21*20} = \frac{8}{15}$

$\frac{7}{10} :\frac{49}{50} = \frac{7*50}{10*49} =\frac{5}{7}$

$\frac{3}{14} : \frac{6}{7} = \frac{3*7}{14*6} = \frac{1}{4}$
