- How do you find common denominators to add and subtract fractions with different denominators?
- How do you find common denominators using a number line?
- How can you teach adding and subtracting fractions with different denominators using a number line?
- How do you find LCD using a number line?
This video explains adding and subtracting fractions with different denominators with and without a number line. Common denominators are found in order to do the calculations. A number line is used to show how common denominators can be found, but the Algebra is shown as well. This is a very good lesson on adding / subtracting fractions.
