a)

6/4 + 3/4 + 2/4 =

6 + 3 + 2/4

11/4

7/4

c)

21/5 + 10/5

21 + 10/5

31/5

d)

4/6 + 2/3 + 1/3 =

2/3 + 2/3 + 1/3

2 + 2 + 1/3

5/3

e)

3/4 + 2/6

3/4 + 1/3==>o mmc de 4,3=12

9 + 4/12

13/12

f)

7/2 - 3/5==>o mmc de 2,5=10

35 - 6/10

29/10

g)

6/4 - 3/8

3/2 - 3/8==>o mmc de 2,8 = 8

12 - 3/8

9/8

Espero ter ajudado.
