**How to Add fractions with like and unlike denominators**

Before we can add these fractions, we'll need to change them so they have the same denominator. To do that, we'll have to find the LCD , or lowest common denominator, of 4 and 3 . It looks like 12 is the smallest number that can be divided by both 3 and 4, so 12 is our LCD .... To add or subtract fractions with different denominators, we need to do some extra steps. The general approach is discussed below. We will go over a few examples in this lesson to make sure you get comfortable with the procedure.

When adding and subtracting fractions, the first thing to check is if the denominators are the same. Adding and Subtracting Fractions with Negatives Once you've learned how to add and subtract positive fractions , you can extend the method to include negative fractions. Note that: âˆ’ 2 3 is the same as âˆ’ 2 3 and 2 âˆ’ 3 âˆ’ 2 âˆ’ 3 simplifies to 2 3 When you are adding or subtracting a... 9/01/2008Â Â· Best Answer: You have to find the LCM, or lowest common denominator for the two denominators. For example: 4/5 times 2/3. The easiest way to find this for most numbers is to multiply them. So 5 times 3 is 15. So if 5 is multiplied by 3, multiply 4 by 3 also to get 12/15. Doing the same â€¦

**Fractions Addition And Subtraction Same Denominators**

Fractions that have exact same denominators are called like fractions. Fractions such as $\frac{1}{5}$ and $\frac{4}{5}$ are like fractions because they have a common denominator 5. In other words, fractions with like denominators are categorized as like fractions.... To add proper or improper fractions with the same denominator: â€¢ add the numerators together â€¢ the denominator stays the same.

To add or subtract fractions with different denominators, we need to do some extra steps. The general approach is discussed below. We will go over a few examples in this lesson to make sure you get comfortable with the procedure.... Adding fractions with different denominators is similar to adding fractions with the same denominators, but you have to do one important thing before you can add them . . . you have to find a common denominator.
