Multiplying and Simplifying Fractions

The video tutorial covers multiplying fractions by canceling common factors. It begins with an example of multiplying 7/5 by 5/6, demonstrating how to cancel the common factor of 5. The next example involves multiplying 12 by 7/15, where the common factor of 3 is canceled to simplify the multiplication. The final example shows multiplying 6/45 by 9, again canceling common factors to simplify the process. Each example emphasizes the importance of reducing fractions before multiplying to make calculations easier.
