Answer 1

Resposta:

c)

Explicação passo a passo:

a) 50 + 20 – 18 : 2 + 16 : 4 = 10

70 - 9 + 4 = 10

61 + 4 = 10

65 = 10

b) 50 + 20 – 18 : 2 + 16 : 4 = 30

70 - 9 + 4 = 30

61 + 4 = 30

65 = 30

c) 50 + 20 – 18 : 2 + 16 : 4 = 65

70 - 9 + 4 = 65

61 + 4 = 65

65 = 65

d) 50 + 20 – 18 : 2 + 16 : 4 = 60

70 - 9 + 4 = 60

61 + 4 = 60

65 = 60
