There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.

Do you need a common denominator for all fractions before doing the order of operations?

You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.


Do you have to have a common denominator when you are adding fractions?

Having a common denominator makes it easier to add or subtract fractions. You can also convert fractions to decimals and then do the addition or subtraction but that is really the same thing as having a common denominator of 10. 100. 1000. etc. Without a common denominator, you would have to mentally make adjustments for the values of fractions. Of course, that is really establishing a common denominator in your head.

Adding unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
