Explicación paso a paso:
7/12 x 4/5 = 28/60 = [tex]\frac{7}{15}[/tex]
2/14 + 3/5= [tex]\frac{10+42}{70} = \frac{52}{70} = \frac{26}{35}[/tex]
[tex]\frac{9}{12} -\frac{2}{4} = \frac{9-6}{12} =\frac{3}{12} =\frac{1}{4}[/tex]
[tex]\frac{5}{6}[/tex] ÷ [tex]\frac{4}{5}[/tex] = [tex]\frac{5}{6} * \frac{4}{5}= \frac{20}{30}= \frac{2}{3}[/tex]
