g)18,25

h)-2,99

Explicação passo a passo:

a) 0,1 + 0,2 + 0,3 =

   0,3 + o,3 =

   0,6

b) 0,35 - 0,4 =

   0,31

c) 1,25 - 6=

  -4,75

d) 7,56 - 5,96=

   1,6

e) 2 - 0,5=

   1,95

f) 7,009 - 1,005=

   6,004

g) 4,6 + 19,77 - 6,12 =

   24,37 - 6,12 =

   18,25

h) 7,58 - 5,59 - 4,98 =

   1,99 - 4,98 =

   -2,99

Answer 2

$\mathbf{\green{\clubsuit}}$ Veja os resultados abaixo:

$\boxed{\begin{array}{lr}\mathbf{\green{a) - 0.4 }}\end{array}}\boxed{\begin{array}{lr}\mathbf{\green{b) - 0.05}}\end{array}} \boxed{\begin{array}{lr}\mathbf{\green{ c)- 4.75}}\end{array}} \\ \boxed{\begin{array}{lr}\mathbf{\green{d)1.58}}\end{array}}\boxed{\begin{array}{lr}\mathbf{\green{e)1.5}}\end{array}}\boxed{\begin{array}{lr}\mathbf{\green{f)6.004}}\end{array}} \\ \boxed{\begin{array}{lr}\mathbf{\green{g)18.34}}\end{array}}\boxed{\begin{array}{lr}\mathbf{\green{h)6.61}}\end{array}}$

☘ Este exercício é bem simples, basta somar ou subtrair. Vamos lá...

A) $\boxed{\begin{array}{lr}\mathbf{\green{0.1 - 0.2 - 0.3}} \\ \mathbf{\green{ \: \: \: \: \: \: 0.1 - 0.5}} \\\mathbf{\green{ \: \: \: \: \: \: \: \: \: - 0.4}} \end{array}}$

• Bem, aqui colocamos o sinal negativo em evidência na expressão!
• E somamos, logo após, o sinal negativo irá à frente, e depois iremos subtrair...

B) $\boxed{\begin{array}{lr}\mathbf{\green{ \: \: \: 0.35 - 0.4}} \\\mathbf{\green{ - (0.4 - 0.35)}} \\ \mathbf{\green{ \: \: \: \: \: \: - 0.05}}\end{array}}$

• Vamos colocar o sinal negativo à frente.
• E depois, subtrair!

C) $\boxed{\begin{array}{lr}\mathbf{\green{ \: \: \: 1.25 - 6}} \\\mathbf{\green{ - (6 - 1.25)}} \\ \mathbf{\green{ \: \: \: \: - 4.75}}\end{array}}$

• Novamente, vamos colocar o sinal negativo à frente.
• E subtrair...

D) $\boxed{\begin{array}{lr}\mathbf{\green{7.56 - 5.98}} \\ \mathbf{\green{ \: \: \: \: \: \: 1.58}}\end{array}}$

• Apenas subtraia...

E) $\boxed{\begin{array}{lr}\mathbf{\green{2 - 0.5}} \\ \mathbf{\green{ \: \: \: \: 1.5}}\end{array}}$

• Subtraia...

F) $\boxed{\begin{array}{lr}\mathbf{\green{7.009 - 1.005}} \\ \mathbf{\green{ \: \: \: \: \: \: \: \: \: 6.004}}\end{array}}$

• Subtraia ;-;

G) $\boxed{\begin{array}{lr}\mathbf{\green{4.69 + 19.77 - 6.12}} \\ \mathbf{\green{ \: \: \: \: \: \: 24.46 - 6.12}} \\\mathbf{\green{ \: \: \: \: \: \: \: \: \: \: \: \: \: 18.34}} \end{array}}$

• Some os números positivos.
• Logo após, subtraia.

H) $\boxed{\begin{array}{lr}\mathbf{\green{7.58 - 5.95 + 4.98}} \\ \mathbf{\green{ \: \: \: \: \: 12.56 - 5.95}} \\\mathbf{\green{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6.61}} \end{array}}$

• Some os números.
• E subtraia.
