Resposta:

9)

a)

$(+ 8) \div ( + 2) = \Large\green{ \bf + 4}$

b)

$( + 9) \div ( + 3) =\Large \green{ \bf \: + 3}$

c)

$( - 12) \div ( + 3) =\Large \green{\bf - 4}$

d)

$( - 18) \div ( - 6) =\Large\green{ \bf + 3}$

e)

$( - 8) \div ( - 4) =\Large \green{\bf + 2}$

f)

$( + 5) \div ( - 1) = \Large \green{\bf - 5}$

g)

$( - 16) \div ( + 4) =\Large \green{\bf - 4}$

h)

$( + 5) \div ( - 5) = \Large \green{\bf- 1}$

10)

$90 \div 3 =\Large \boxed{\red{ \bf \: 30 \: }} \\ 30 \div ( - 2) = \boxed{ - 15} \\ ( - 15) \div ( - 5) =\Large \boxed {\bf \red 3} \\ 3 \times 30 = \boxed{ 90}$

$( - 12) \div 2 = \Large \boxed {\bf \green{ - 6}} \\ ( - 6) \div ( - 3) = \Large \boxed {\green{ \bf \: 2 \: }} \\ 2 \div 2 =\Large \boxed {\green{\bf \: \: 1 \: \: } } \\ 1 \times ( - 12) = \boxed { \: - 12 \: } \\\\ \Large \boxed{\underline{\blue{\bf Bons \:Estudos!}}}\\\\ \Large \boxed{\underline{\bf 22/05/2021}}$
