Answer 1

Boa Tarde !

A) (+ 8 ) ÷ ( + 2 ) = + 4

b) ( + 30 ) ÷ ( +10 ) = + 3

c) ( – 12 ) ÷ ( – 3 ) = + 4

d) ( – 20 ) ÷ ( – 10 ) = + 2

e) ( + 5 ) ÷ ( – 1 ) = - 5

f) ( +15 ) ÷ ( – 5 ) = - 3

g) ( – 10 ) ÷ ( + 2 ) = - 5

h) ( – 4 ) ÷ ( + 1 ) = - 4

i) ( – 10:) ÷ ( – 1 ) = + 10

j) ( – 4 ) ÷ ( – 4 ) = + 1

k) ( + 24) ÷ ( – 6 ) = - 4

l) ( – 18 ) ÷ ( – 1 ) = + 18

m) ( + 15 ) ÷ ( + 1 ) = + 15

n) ( + 18 ) ÷ ( + 9 ) = + 2

Basta aplicar essa seguinte regra :

( + ) ( + ) = +

( - ) ( - ) = +

( + ) ( - ) = -

( - ) ( + ) = -
