Resolução:

a)

1/2 + 2/3 = mmc 2, 3 = 6

3 + 4/6

7/6

b)

5/6 + 2/3 = mmc 6, 3 = 6

5 + 4/6

9/6 ÷ 3/3

3/2

c)

4/5 + 2/3 = mmc 5, 3 = 15

12 + 10/15

22/15

d)

9/2 + 7/4 + 2/3 =mmc 2, 4, 3 = 12

54 + 21 + 8/12

83/12

e)

2/5 + 1/10 + 1/2 = mmc 5, 10, 2 = 10

4 + 1 + 5/10

10/10 ÷ 10/10

1

f)

2/7 + 1/10 + 3/2=mmc 7, 10, 2 = 70

20 + 7 + 105/70

132/70 ÷ 2/2

66/35

Boas lições.
