Answer 1

Resposta:

1 )16/-8= -2

2) -20/-5= 4

3) -24+15/3= -19

4) [ -8-4.-3/-2

-12.-3/-2

4/-2= -2

5) -5/ [ -3.9 ]

-5/-27= 0,185...

Answer 2

( -4 + 20 ) : ( -8)=

16 : -8 =

-2

(-6 - 14 ) : ( -6 + 1 )=

-20 : -5 =

4

(-8) . (+3) - ( -15) : ( +3)=

-24 - (-3) =

-24 + 3  =

-21

[ -8 + ( -4) . ( -3) ] : ( -1 - 1)=

[-8 + 12] : -2 =

4 : -2 =

-2

( -6 - 2 +3 ) : [ -3 . ( -2 + 3) +8 ] =

-5 : [ -3 * 1 + 8 ] =

-5 : [ -3 + 8 ] =

-5 : 5 =

-1
