Resposta:

3)

1/2 = 0, 500

5/6 = 0, 833

1/12 = 0, 083

1/3 =  0, 333

1/12         1/3       1/2       5/6

4)

a) 3/10 + 4/10 =

3 + 4 / 10 = 7/10

b) 2/7 + 3/7 =

2 + 3 / 7 =  5 / 7

c) 5/12 + 3/12 + 1/12 =

5 + 3 + 1 / 12 =  9/12 ( simplificando por 3);

3/4

d) 5/7 - 2/7 =

5 - 2 / 7 =  3/7

e)  3/5 - 2/5 =

3 - 2 /5 =  1/5

f)  14/ 20 - 2/20 - 1/20 =

14 - 2 - 1 / 20 =  11/20
