This video indicates it is for pre-algebra, however this video would be good for anyone who is reviewing or learning division of fractions. In the video division of fractions starts with dividing a whole number by a fraction. The instructer uses a number line to show this concept, then does the problem, when doing the problem he uses the reciprocal and then multiplies. He does a few examples using both of these methods. Then they move on to the problem, change division to multiplication, cross cancel, and then multiply. Once again they do a number of examples. Video is good quality and good for all students as review or initial learning of the concept.
