9+3w/11 divided by 25w75/121
Do I need a Common denominator?
Would it be 121 as 11x11 is 121?
Do I then multiply the numeratos 9+3w by 11 or do I do the addition of 9+3w for12w?

No, in division and multiplication you do not need a common denominator.
Remember that when you divide by a fraction you instead multiply by the reciprocal of that fraction
so...
(9+3w)/11 divided by (25w75)/121
=(9+3w)/11 * 121/(25w75)
=3(3+w)/11 * 121/(25(w3))
=33/25 , with x not equal to 3
