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.
Because if there's no common denominator it'll be hard to simplify. And will cause you to get a headache.
You don't need a common denominator to divide 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.

You need a common denominator for both.
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.
Because the answers will be wrong when adding or subtracting them if they don't have a common denominator.
The first step to take is find the lowest common denominator of the fractions which can be done by finding the lowest common multiple of the numbers.

Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
You don't need a common denominator to divide fractions.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
Adding fractions. 1/5 + 1/2 need a common denominator to add.
