Here is a great video explaining multiplying a fraction by a whole number. Sal shows students how to put a whole number over 1 to multiply it by a fraction. He simplifies his answer and writes it as a mixed number.

This video on changing improper fractions to mixed numbers would nicely compliment the Khan Academy video on writing mixed numbers as improper fractions. Sal first shows students how to convert improper fractions. Then, he uses drawings...

A step-by-step explanation about improper fractions being changed into mixed numbers. The instructor uses diagrams in several examples which gives a visual explanation of the equation.
