Question

4 - Calcule as divisões dos números inteiros:


a) ( - 20 ) : ( - 4 ) =


b) ( + 8 ) : ( + 2 ) =


c) ( - 12 ) : ( + 6 ) =


d) ( - 21 ) : ( + 7 ) =


e) ( +18 ) : ( + 3 ) =


f) ( - 10 ) : ( + 5 ) =

g) ( + 100 ) : ( - 4 ) =​

Answer 1

Resposta:

a) (-20) : (-4) = 5

b) ( + 8 ) : ( + 2 ) = 8 : 2 = 4

c) ( - 12 ) : ( + 6 ) = -12 : 6 = -2  

d) ( - 21 ) : ( + 7 ) = -21 : 7 = -3

e) ( +18 ) : ( + 3 ) = 18 : 3 = 6  

f) ( - 10 ) : ( + 5 ) = -10 : 5 = -2  

g) ( + 100 ) : ( - 4 ) =​ 100 : (-4) = -25
