Answer 1

Resposta:

a ) ( - 15 ) ÷ ( + 5 ) = - 3

b ) ( + 32 ) ÷ ( + 4 ) = + 8

c ) ( - 20 ) ÷ ( - 20 ) = + 1

d ) ( + 18 ) ÷ ( - 2 ) = - 9

e ) ( - 37 ) ÷ ( + 37 ) = - 1

f ) ( - 44 ) ÷ ( - 2 ) = + 22

g )( - 25 ) ÷ ( + 5 ) = - 5

h ) 0 ÷ ( - 10 ) = 0

i ) ( - 75 ) ÷ ( - 5 ) = + 15

j ) ( - 96 ) ÷ ( + 6 ) = - 16

k ) ( + 84 ) ÷ ( + 21 ) = + 4

l ) ( + 39 ) ÷ ( - 13 ) = - 3

m ) ( - 144 ) ÷ ( - 24 ) = + 6

n ) ( + 200 ) ÷ ( - 25 ) = - 8

o ) ( + 125 ) ÷ ( + 25 ) = + 5

p ) ( - 294 ) ÷ ( + 49 ) = - 6

Basta aplicar essa regra :

( + ) ( + ) = +

( - ) ( - ) = +

( + ) ( - ) = -

( - ) ( + ) = -
