D) 3/4 + 1/2 - 1/3 - 1/6
I) 2/5 + 1/2 - 3/10 + 1/4

Answer 1

Resposta:

3/30 + 5/30= 8/30 =4/15

9/24 ± 4/24= 13/24

3/6 + 2/6 + 5/6= 10/6= 5/3

9/12 + 6/12 - 4/12 - 2/12= 9/12= 3/4

8/20 + 10/20 - 6/20 + 5/20= 17/20

Answer 2

Olá...

a)

1/10 + 1/6  ⇒mmc = 30

3 + 5/30

8/30 ÷ 2

4/15

b)

3/8 + 1/6⇒ mmc = 24

9 + 4/24

13/24

c)

1/2 + 1/3 + 5/6  ⇒ mmc = 6

3 + 2 + 5/6

10/6 ÷ 2

5/3

d)

3/4 + 1/2 - 1/3 - 1/6 ⇒mmc = 12

9 + 6  - 4 - 2/12

15 - 6/12

9/12

e)

2/5 + 1/2 - 3/10 + 1/4⇒mmc = 20

8 + 10 - 6 + 5/20

23 - 6/20

17/20
