Common 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. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Adding fractions with like denominators is straightforward, as you simply add the numerators while keeping the denominator the same. In contrast, adding fractions with unlike denominators requires finding a common denominator, which involves identifying the least common multiple of the denominators. Once a common denominator is established, you convert each fraction accordingly before adding the numerators. This extra step makes the process more complex compared to adding fractions with like denominators.

maths
A common denominator is needed when adding or subtracting fractions of different denominators.
When adding or subtacting fractions make sure that the denominators are of the same values if they are not then find the lowest common denominator.
In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
