For both of them you just make them into fraction.
For #2

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



21
----
80
is that answer because it can't be simplified
after that
Y = kx
@ y = 216, x = 2
k = y/x = 216/2 = 108
@ x=7
y = (108)(7) = 756
Answer:
its b
