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.

good answer, thx!

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.

To add unlike fractions - fractions with different denominators - you first convert the fractions so they have the same denominator. After that, it's exactly the same as adding fractions which have the same denominator from the start.

Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same 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.

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.

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

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.

fractions having same denominators are like fractions & others are unlike fractions

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.

no, to add and subtract like and unlike fractions the denominator has to be the same,

you must make the fractions equivalent and with the same denomenator
