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.

How is adding like fractions and adding unlike fractions the same?

What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
What is a unlike fraction?
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
Why do you need a common denominator when adding fractions?
because you can not add unlike thingsTo get the right answer. It's not immediately obvious what the sum of 1/2 and 1/3 is. But if you realize that 1/2 = 3/6 and 1/3 = 2/6, then 1/2 + 1/3 = 3/6 + 2/6 = 5/6
How do you add unlike denominators?
When there are different denominators in fractions, to add them, it is necessary to find a common denominator. Usually this occurs by multiplying them, such as 1/3 + 1/2 would equal 2/6 + 3/6, which becomes 5/6.
