Example 2:

To write a mixed number as an improper fraction using multiplication and addition:

Terence worked weeks during the summer. Find the improper fraction that represents how many weeks Terence worked.

First, find the numerator of the improper fraction by multiplying the denominator by the whole number, and then adding the numerator.

The denominator is the same as in the mixed number, so write 7 as the denominator of the improper fraction.

Terence worked weeks during the summer.
