For both of them you just make them into fraction.
For #2
[tex] \frac{36}{120} [/tex]
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100
so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100
The answer is 30%
For number #3
you simply put 63 over 240
63
-----
240
[tex]63 \div 3= 21[/tex]
[tex]240 \div 3 = 80[/tex]
[tex] \frac{21}{80} [/tex]
21
----
80
is that answer because it can't be simplified
after that
