Another way we see division problem is in a fraction form. In that case the
top fraction stays the same. The bottom fraction gets changed to its
reciprocal.

*** The answer can be left as an improper fraction or can be changed back

Remember when working with whole numbers and fractions make the whole
number a fraction by placing the number over one.
