Multiplying and Simplifying Fractions

This tutorial from ajspeller.com teaches how to multiply fractions using a technique called cross canceling. The video provides four examples, demonstrating how to simplify fractions before multiplying. The first example shows multiplying 5/6 by 3/10, the second example covers 2/7 by 3/4, the third example involves 4/9 by 5/8, and the final example is 2/3 by 4/5. The tutorial emphasizes that not all fraction multiplications will involve cancellations.
