How to Multiply Fractions
This video shows how to use the standard algorithm and a neat shortcut to find the answer.
- This is a great video that shows how to use the standard algorithm. It also shows a neat shortcut to get the same answer. I found that this shortcut cannot be used when multiplying unit fractions. It also cannot be used when multiplying all fractions. Only certain fractions work when using this shortcut.
This video shows how to use grids
- This video shows how and why the grid method works. It also shows different ways to use grids. This video shows different problems or equations and shows how to solve each one. It shows more than unit fractions like 1/3.
This video shows how to multiply fractions using a number line.
- This video shows how to use the number line. She shows that number lines can be written in different ways to get the same answer. She also shows why using a number line works and why each number line works. Both number lines show the same problem and the same solution.
