Adding unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator .

Then add and simplify.

When adding fraction do you need a common denominator?

Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!


Why do you need a common denominator?

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.


How are lcm's used in adding or subtracting fractions?
