(-7/8) (1/9)=
(5/6) (-3/7)=
(1/2) (-4/5)=
(-3/4) (2/3) (-1/2)=
me ayudan?

Answer 1

$( - \frac{ 7}{8} )( \frac{1}{9} ) = - \frac{7}{72}$

$( \frac{5}{6} ) ( - \frac{3}{7} ) = - \frac{ 15}{42} = - \frac{5}{14}$

$( \frac{1}{2} )( - \frac{4}{5} ) = - \frac{4}{10} = - \frac{2}{5}$

$( - \frac{3}{4} )( \frac{2}{3} )( - \frac{1}{2} ) = \frac{6}{24} = \frac{1}{4}$

Espero haberte ayudado. Suerte en los estudios ≧◠◡◠≦.
