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.
Adding fractions is achieved by adding the numerators as long as the denominators are the same. When the denominators are the same the fractions are "like fractions".
With different denominators they are "unlike fractions"; to be able to add them they need to be converted in to equivalent fractions with the same denominators. They are then "like fractions" and can be added.

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.
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.
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.
Do you need a common denominator when adding fractions?
Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
What is the procedure for adding and subtraction fracions?
1) Convert the fractions to equivalent fractions, to ensure they have the same denominator. 2) Once they have the same denominator, just add or subtract the numerators. 3) As with most problems with fractions, check whether you can simplify the final result.
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.
How are like fractions and unlike fractions different?
Like fractions have the same denominator, unlike fractions don't.
Does the denominator have to be the same when adding a fraction?
When adding two or more unlike fractions, yes.
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.
What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
What do like and unlike fractions mean?
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
What must you do first before adding or subtracting unlike fractions?
you must make the fractions equivalent and with the same denomenator
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
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.
How do you solve a fraction problem when you don't have the same denominator?
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
Before adding or subtracting Why are fractions turned into like fractions?
They have to have the same denominator.
When adding two fractions with unlike denominator's which of these steps is the first step?
The first step is to make the denominators the same.
