Answer 1

Olá...

Resolva as operação com frações:

a)

3/5 + 1/5 ⇒ mmc = 5

3 + 1/5

4/5

b)

6/9 - 3/9 ⇒mmc = 9

6 - 3/9

3/9 ÷ 3

1/3

c)

1/3 + 2/7 ⇒ mmc = 21

7 + 6/21

13/21

d)

6/4 + 1/9 + 2/3

3/2 + 1/9 + 2/3 ⇒ mmc = 18

27 + 2 + 12/18

41/18

e)

7/5 - 1/3 ⇒ mmc = 15

21 - 5/15

16/15

f)

8/10 - 1/4

4/5 - 1/4 ⇒mmc = 20

16 - 5/20

11/20

g)

3/6 + 1/2

1/2 + 1/2 ⇒ mmc = 2

1 + 1/2

2/2

1

h)

2/12 + 1/6

1/6 + 1/6 ⇒mmc = 6

1 + 1/6

2/6 ÷ 2

1/3

i)

7/9 - 2/5 ⇒mmc = 45

35 - 18/45

17/45

Bons estudos.
