(5/6) (-3/7)=
(1/2) (-4/5)=
(-3/4) (2/3) (-1/2)=
ayuda pls​

Answer 1

Explicación paso a paso:

$( - \frac{7}{8} )( \frac{9}{1} ) = \frac{ - 7 \times 9}{8 \times 1} = - \frac{63}{8}$

$( \frac{5}{6} )( - \frac{3}{7} ) = \frac{5 \times -3}{6 \times 7} = \frac{5 \times - 1}{2 \times 7} - \frac{5}{14}$

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

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