Resposta:

A) 50

B) 2

C) 53

D) 32

E) 156

F) 2.128

Explicação passo-a-passo:

A) 27 : 9 + (12 × 4 - 1) =

27 : 9 + ( 48 - 1) =

27 : 9 + 47 =

3 + 47 = 50

B) (100 : 5 + 2 × 10) : (8 × 10 - 15 × 4) =

(20 + 20) : (80 - 60 ) =

40 : 20 = 2

C) 3 + 12 × 6 - 4 × 5 + 12 : 6 =

3 + 72 - 20 + 2 =

75 - 22 = 53

D) (3 × 19 - 4 × 5 : 2) - 5 × 3 =

(57 - 20 : 2) - 5 × 3 =

(57 - 10) - 5 × 3 =

47 - 5 × 3 =

47 - 15 = 32

E) 327 : 3 + (125 × 2 : 10 + 22) =

327 : 3 + (250 : 10 + 22) =

327 : 3 + (25 + 22) =

327 : 3 + 47 =

109 + 47 = 156

F) ( 358 - 324) : 17 + (87 × 2 - 39 × 4) : 6 =

34 : 17 + (174 - 156) : 6 =

34 : 16 + 18 : 6 =

2.125 + 3 = 2.128
