Answer:

160/117

Step-by-step explanation:

1/3+1/13

(LCM: 39)

(1/3)*13+(1/13)*3

=13/39+3/39

=(13+3)/39

=16/39

7/9+5/6

(LCM: 18)

(7/9)*2+(5/6)*3

14/18+18/18

=(14+18)/18

=32/18

=16/9

16/39 from 16/9

=16/9-16/39

(LCM: 117)

(16/9)*13-(16/39)*3

=208/117-48/117

=(208-48)/117

=160/117

therefore answer is 160/117.

Answer 2

Step-by-step explanation:

1/3 + 6/13 = (13+18)/39 = 31/39

7/9 + 5/6 = (14+15)/18 = 29/18

29/18 - 31/39 = (377+186)/234 = 563/234

= 2 whole 95/234
