Answer 1

Respuesta:

Transforma la división en multiplicación y resuelve.

$\frac{6}{8}:\frac{6}{7} = \frac{6*7}{8*6} =\frac{42}{48} =\frac{21}{24}=\frac{7}{8}$

$\frac{25}{14}:\frac{10}{7} = \frac{25*7}{14*10} =\frac{175}{140} =\frac{35}{28}$

$\frac{7}{9}:\frac{21}{4} = \frac{4*7}{9*21} =\frac{28}{189} =\frac{4}{27}$

$\frac{7}{8}:\frac{14}{24} =\frac{24*7}{8*14} =\frac{168}{112} =\frac{84}{56}=\frac{42}{28}=\frac{21}{14}=\frac{3}{2}$

Divide mediante producto de extremos y medios.

$\frac{6}{5}:\frac{12}{10}=\\\\\frac{\frac{6}{5}}{\frac{12}{10}} =\frac{6*10}{12*5} =\frac{60}{60}=1$

$\frac{20}{3}:\frac{15}{6}=\\\\\frac{\frac{20}{3}}{\frac{15}{6}} =\frac{20*6}{15*3} =\frac{120}{45}=\frac{24}{9}=\frac{8}{3}$
