J) 13/6 + 4/6 - 3/6= ​

Answer 1

Olá....

Resolução:

a)

3/4 - 2/4 ⇒ mmc = 4

3 - 2/4

1/4

b)

1/6 + 5/4 + 3/2⇒mmc de (6, 4, 2) = 12

2 + 15 + 18/12

35/12

d)

3/5 + 7/3 ⇒mmc de( 5, 3) = 15

9 + 35/15

44/15

e)

1/8 + 10/4

1/8 + 5/2⇒mm de (8,2) = 8

1 + 20/8

21/8

f)

5 1/3 + 4 1/6

16/3 + 25/6⇒mmc de (3, 6) = 6

32 + 25/6

57/6 ÷ 3

19/2

g)

6/3 - 1/2

2 - 1/2⇒mm = 2

4 - 1/2

3/2

h)

1 4/3 + 3 2/3

7/3 + 11/3⇒mmc = 3

7 + 11/3

18/3

6

i)

11/7 + 3/4 - 1/2⇒mmc de (7 + 4 - 2) = 28

44 + 21 - 14/28

65 - 14/28

51/28

j)

13/6 + 4/6 - 3/6 ⇒ MMC = 6

13 + 4 - 3/6

17 - 3/6

14/6 ÷ 2

7/3
