Usually, to find a mixed number answer, you divide 81 (in this case) by 3, and write the answer as the integer part of the mixed number, and the remainder over 3 as the fractional part of the mixed number. However, since 81 divided by 3 is 27, with no remainder, there is no reason to write it as a mixed number. It could be written as 27 and 0/3, but this is not generally the accepted way to write an answer to a division problem that does not involve a remainder.
