Question 1
Reading question as:-
5/a - 3/b + 2 / (ab)
= (5b - 3a + 2) / ab
Question 2
Reading question as:-
(5n + 1) / 6 + (3n - 2) / 8
= (20n + 4)/24 + (9n - 6)/24
= (29n - 2) / 24
Question 3
Reading question as:-
[ (x + 5) / 3 ] / [ (x - 3) / 2 ]
= [ 2.(x + 5) ] / [ 3.(x - 3) ]
= (2/3).(x + 5) / (x - 3)
Suggestion
Brackets are required to avoid misunderstanding of original questions.

1. 5b/5ab - 3a/3ab (You have to make it so that the denominator will be the same... whatever you do to the denominator, you have to do to the numerator.)
2 and 3 are similar...
just use equivalent fractions and figure it out. Good luck.

Ooooh, it looks like somebody's trying to cheat on their homework. How about you open your math book and look up the instructions on how to do the problem? There's a novel concept.
