d) (+12) : (+4) =
e) (+ 40) : (- 5) =
f) (- 12) : (- 30) =
g) (- 64) : (+ 8) =
h) (- 24) : (- 2) =
por favor o calculo
Soluções para a tarefa
- 6 = + 3
- 2
*************************************
b) (+ 8) : (- 4) = - 2
+ 8 = - 2
- 4
*************************************
c) (- 10) : (+ 4) =
- 10 (:2) = - 5
+ 4 (:2) 2
_______________________________
d) (+12) : (+4) = + 3
+ 12 = + 3
+ 4
___________________________
e) (+ 40) : (- 5) = - 8
+ 40 = - 8
- 5
________________________
f) (- 12) : (- 30) = + 2/5
- 12 (: 6) = + 2
- 30 (: 6) 5
*********************************************
g) (- 64) : (+ 8) = - 8
- 64 (: 8) = - 8 = - 8
+ 8 (: 8) 1
*********************************************
h) (- 24) : (- 2) = + 12
- 24 (: 2) = - 12 = + 12
- 2 (:2) - 1
Resposta:
a) (- 6) : (- 2) = + 3
