Regra de sinal :
( - ) ( - ) = +
( + ) ( + ) = +
( - ) ( + ) = -
( + ) ( - ) = -
→ Cálculo :
A) ( + 12 ) ÷ ( - 6 ) =
- ( 12 ÷ 6 ) =
-2
B) ( - 8 ) ÷ ( - 4 ) =
+ ( 8 ÷ 4 ) =
+2
C) ( + 120 ) ÷ ( + 12 ) =
+ ( 120 ÷ 12 ) =
+10
D) ( - 25 ) ÷ ( - 5 ) =
+ ( 25 ÷ 5 ) =
+5
E) ( + 48 ) ÷ ( - 6 ) =
- ( 48 ÷ 6 ) =
-8
F) ( - 200 ) ÷ ( - 10 ) =
- ( 200 ÷ 10 ) =
-20
