How do you simplify (3/a)+3 divded by (3/a)-3

so it kinds looks like this and I cannot find nothing online to help me....
3
--- +3
a
-------------
3
--- -3
a


and I also have

5 + 6
--- -----
x x^2
------------------------------
25 - 36
---- ------
x^2 x


I have my final today and need to know now to do this before 7pm!! please help!!

3+3a
---------
a
---------------
3-3a
--------
a

3+3a
--------------
3-3a

3(1+a)
------------------
3(1-a)

(1+a)
------------------
(1-a)
For the second one,

5x+6
-----------
xx^2
-------------------------
25-36x
-------------
x^2x


5x+6
----------------
25-36x

(3/a)+3 divded by (3/a)-3

you know, its almost easier to solve that way
multiply both parts by a
(3)+3a divided by (3)-3a

3+3a divided by 3-3a

now the 'compound part is gone
(3+3a)/(3-3a)

factor out a 3
(1+a)/(1-a)


and
5/x+6/x^2 divided by 25/x^2-36/x

multiply 5/x by '1'
in the form of x/x
5x/x^2+6/x^2 divided by 25/x^2-36/x

same thing for 36/x
5x/x^2+6/x^2 divided by 25/x^2-36x/x^2

since all the denominators are x^2
they magically disappear
leaving
(5x+6)/(25-36x)

[cannot reduce this like the first one]
