Factor each
3x^3=3*x*x*x
21x^2=3*7*x*x
36x=2*2*3*3*x
factor out 3x
3x(x^2-7x+12)
what 2 numbers multiply to get 12 and add to get -7?
-3 and -4
3x(x-3)(x-4)
It is: 91/200, because 45.5/100 is 45.5% as a fraction, but you have to make both the top a whole number, so you can multiply 45.5 by 2 to get 91, then also times the bottom by 2, and you get 200!
