Respuesta:

[tex]A:\frac{2}{7} =\frac{14}{2} --->A =\frac{14}{2} .\frac{2}{7}---> A =\frac{28}{14} =2[/tex]

Comprobamos:

[tex]2.\frac{2}{7} =2.\frac{7}{2} =\frac{14}{7}[/tex]

[tex]\frac{4}{9} :B =\frac{20}{18} ---> \frac{\frac{4}{9} }{\frac{20}{18} } =B--->\frac{2}{5} =B[/tex]

Comprobamos:

[tex]\frac{4}{9} :\frac{2}{5} =\frac{4}{9} .\frac{5}{2} =\frac{20}{18}[/tex]

[tex]C:\frac{7}{12} =\frac{24}{21} --->A =\frac{24}{21} .\frac{7}{12}---> A =\frac{168}{252} =\frac{2}{3}[/tex]

Comprobamos:

[tex]\frac{2}{3} :\frac{7}{12} =\frac{2}{3} .\frac{12}{7} =\frac{24}{21}[/tex]

[tex]\frac{8}{11} :D =\frac{8}{55} ---> \frac{\frac{8}{11} }{\frac{8}{55} } =D--->5 =B[/tex]

Comprobamos:

[tex]\frac{8}{11} :5 =\frac{8}{11} .\frac{1}{5} =\frac{8}{55}[/tex]
