[-3/32]×[-8/9]×[-27/9]
[-25/18]×49/10×[-4/35]
Vă rog ajutor am nevoie urgent !!!!

(-3/32)x(-8/9)x(-27/9)=

=(-3/32)x(-8/9)x(-3)=

=-(3/32)x(8/3)=

=-(1/4)x(1/1)=

=-1/4

(-25/18)x49/10x(-4/35) =

= 25/18x49/10x4/35 =

=1/9x7/1x1/1 =

=7/9

( - 3 / 32 ) ×  ( - 8 / 9 ) × ( - 27 / 9 ) = - 1 / 4

= -  ( 3 × 8 × 27 ) / ( 32 × 9 × 9 )  =

= - ( 8 × 81 ) / ( 32 × 81 ) =

= -  1 / 4

__________________________

( - 25 / 18 ) ×  49 / 10 × ( - 4 / 35 ) = 7 / 9

= + ( 25 × 49 × 4 ) / ( 18 × 10 × 35 ) =

= ( 100 × 49 ) / ( 10 × 630 ) =

= ( 100 × 49 ) / ( 100 × 63 ) =

= 7 / 9
