Answer 1

Resposta:

a) 8.3

a) 8.3b) 4.3

a) 8.3b) 4.3c) 9.01

a) 8.3b) 4.3c) 9.01d) 14.83

a) 8.3b) 4.3c) 9.01d) 14.83e) 184.33

a) 8.3b) 4.3c) 9.01d) 14.83e) 184.33f) 136.49

Explicação passo-a-passo:

a) 12/4 + 53/10 = 60/20 + 106/20 = 16.6/2 = 8.3

b) 78/10 - 7/2 = 78/10 - 35/10 = 43/10 = 4.3

c) 127/10 + 24/5 - 849/100 = 1270/100 + 480/100 - 849/100 = 901/100 = 9.01

d) 3574/100 - 2116/100 + 2/8 = 14296/400 - 8464/400 + 100/400 = 5932/400 = 59.32/4 = 14.83

e) 135 + 49.33 = 184.33 ( essa é suave então dá pra fazer na soma mesmo )

f) 2163/10 - 7981/100 = 21630/100 - 7981/100 = 13649/100 = 136.49
