x = 12
so the difference is 333.96 - 253 namely 80.96.
now, if we take 253 to be the 100%, what is 80.96 off of it in percentage?
to convert a mixed number of the form a b/c for an improper fraction, you will get (ac+b)/c. use this on the two fractions to get 4/3 to 5/3. "to" is just another word for "divided by" or "over". so, we can do 4/3 divided by 5/3, and if you multiply both numbers by 3, it will not change the result, because you are multiplying by 3/3 or 1, so you will get your final answer is 4/5.
