Special notes

• If the second factor is a whole number, remember
  that all whole numbers can be written in fraction
  form by putting them over the denominator of 1.
• The inverse of whole numbers is the same number
  as the denominator and 1 as the numerator.

The inverse of 4 is

To find the inverse of a mixed number

• First convert the mixed number into an improper
  fraction.
• Then flip the numerator and the denominator with
  each other to find the inverse.
