Question

(-2/5) * (-3/4)=
(-1/3) * (-76) * (-3)=
-6*-3*-3/4*-0.2*-1=
(49) / ( )= -7

Answer 1

Respuesta:

$- \frac{2}{5} \times - \frac{3}{4} = \frac{6}{20} = \frac{3}{10}$

Explicación paso a paso:

$( - \frac{1}{3}) \times ( - 76) \times ( - 3) = ( - \frac{1}{3}) \times ( - \frac{76}{1} ) \times ( - \frac{3}{1} ) =- \frac{228}{3} = - 76$

$( - 6) \times ( - 3) \times ( - \frac{3}{4} ) \times ( - 0.2) \times ( - 1) = ( - \frac{6}{1} ) \times ( - \frac{3}{1} ) \times ( - \frac{3}{4} ) \times ( - \frac{1}{5} ) \times ( - \frac{1}{1} ) = - \frac{54}{20} = - \frac{27}{10}$

49/x = -7

x=49/-7

x=-7
