Answer 1

Resposta:

a) 8,0 + 0,3

b) 14,0 + 0,2

c) 34,0 + 0,6

d)7,000 + 0,400 + 0,020 + 0,003

Answer 2

Resposta:

8,3 = 8.1 + 3.(1/10) = 8 + 3/10

14,2 = 1.10 + 4.1 + 2.(1/10) = 10 + 4 + 2/10

34,6 = 3.10 + 4.1 + 6.(1/10) = 30 + 4 + 6/10

7,423 = 7.1 + 4.(1/10) + 2.(1/100) + 3.(1/1000) = 7 + 4/10 + 2/100 + 3/1000
