You relate the given part value to the given total value,


and then multiply this fraction / (this ratio) by 100  to get percentage


   percent = %284.096%2F189.6%29%2A100 = 2.16%.


You may round it on your way.

After completing my solution, I want to make couple of notices. 

1)  The number of households is irrelevant to the solution.

    It is an excessive, non-necessary number.



2)  You write the number 4,096 INCORRECTLY in your post.

    The correct writing is  4.096.


    When you write as you write, you demonstrate that you don't know very basics of Mathematical writing.
