Soluciones:

$a) \ \dfrac{2}{7}: \dfrac{4}{3}= \dfrac{2*3}{4*7}= \dfrac{6}{28}= \dfrac{3}{14} \\ \\ \\ b) \ \dfrac{5}{9}: \dfrac{10}{3}= \dfrac{5*3}{10*9}= \dfrac{15}{90}= \dfrac{1}{6} \\ \\ \\ c) \ \dfrac{3}{8} :\dfrac{5}{2}= \dfrac{3*2}{5*8}= \dfrac{6}{40}= \dfrac{3}{20} \\ \\ \\ d) \ \dfrac{2}{3}: \dfrac{4}{5}= \dfrac{2*5}{4*3}= \dfrac{10}{12}= \dfrac{5}{6} \\ \\ \\ e) \ \dfrac{13}{2} :\dfrac{5}{8} = \dfrac{13*8}{5*2}= \dfrac{104}{10}= \dfrac{52}{5}$
