Yes.
No only when adding or subtracting fractions a common denominator is needed
No, You only need a common denominator when adding or subtracting 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.
Because if there's no common denominator it'll be hard to simplify. And will cause you to get a headache.
You need a common denominator for both.

Find a common denamonator.
No, You only need a common denominator when adding or subtracting 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.
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.
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
Adding fractions. 1/5 + 1/2 need a common denominator to add.
When you are adding or subtracting unlike fractions.
Because the answers will be wrong when adding or subtracting them if they don't have a common denominator.
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.
