Understanding Fractions and Division

The video tutorial explains how to simplify complex fractions, which are fractions over fractions, by using division. It introduces the 'keep, change, flip' method for manual calculations and demonstrates how to use a calculator for fraction division. A word problem is solved to find average speed, emphasizing the importance of order in division. The tutorial concludes with a review of key points, highlighting the need to rewrite complex fractions as division problems and the significance of understanding the order of operations in word problems.

What is a complex fraction?
