Adding & Subtracting Frations

Explanation

1. You look at your Fractions.If the Fractions do not have a common denominator then you have to list the multiples of each number.


2. Once you find a common multiple between the denominators that number becomes the new denominator.


3. Then you multiply the numerator as many times as you multiplied the denominator and what you get is your new numerator.


4. Then you add or subtract across,but your denominators stay the same your just adding the numerator.


5.Then you simplify (If you need too)


6. And thats how you add and subtract fractions.
