To write a mixed number as an improper fraction, use the following procedure:
First, write the whole number 5 as a fraction with its denominator equal to 100:
Multiply 5*100:
Rewrite the mixed fraction using this representation for the number 5:
Since they have the same denominator, add the fractions 500/100 and 27/100 (let the denominator unaltered):
Since 527 and 100 have no common divisors, that fraction cannot be reduced.
Therefore:
