(6+2)+(5/8 + 3/4)

8 + 11/8

8 + 1 3/8

8 + 1 + 3/8

9 + 3/8

=9 3/8

b. 8 3/4 - 5 2/3

(8-5)+(3/4 - 2/3)

3 + 1/12

=3 1/12

c. 8 3/10 - 3 4/5

83/10 - 19/5

=9/2

d. 3 2/5 + 6 8/10 + 2 12/18

(3 + 6 + 2) (2/5 + 8/10 + 12/18)

11 + 28/15

11 + 1 13/15

11 + 1 + 13/15

12 + 13/15

= 12 13/15

e. 7 + 2 1/6

7 + 2 + 1/6

9 + 1/6

= 9 1/6

f. 8 6/9 + 12 4/18 - 2 1/3

8 + 6/9 + 12 + 4/18 - (2 + 1/3)

8 + 6/9 + 12 + 4/18 - 2 - 1/3

(8 + 12 - 2)+(6/9 + 4/18 - 1/3)

18 + 5/9

=18 5/9

g. 30 4/9 + 24 9/12 - 20 3/5

30 + 4/9 + 24 + 9/12 - (20 + 3/5)

30 + 4/9 + 24 + 9/12 - 20 - 3/5

(30 + 24 - 20)+(4/9 + 9/12 - 3/5)

34 + 107/180

= 34 107/180

h. 11 3/8 + 8 5/6 - 7 7/12

11 + 3/8 + 8 + 5/6 - (7 + 7/12)

11 + 3/8 + 8 + 5/6 - 7 - 7/12

(11 + 8 - 7)+(3/8 + 5/6 - 7/12)

12 + 5/8

= 12 5/8

eso es todo, ojalá entiendas y te ayude.
