Answer 1

Olá....

a) 7/6 + 4/3 ⇒mmc = 6

7 + 8/6

15/6

b) 9/5 - 6/7 ⇒mmc = 35

63 - 30/35

33/35

c) 1/7 + 4 ⇒ mmc = 7

1 + 28/7

29/7

d) 5/12 + 5/6 - 3/4 ⇒mmc = 12

5 + 10 - 9/12

6/12 ÷ 6

1/2

e) 9/10 + 4/5 + 5/2⇒mmc = 10

9 + 8 + 25/10

42/10 ÷ 2

21/5

f) 4/9 + 1 - 2/3 ⇒mmc = 9

4 + 9 - 6/9

7/9

Espero ter ajudado.
