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.
The answer depends on what you need t do with the fraction.

You need to learn it, so you can learn Greatest Common Factor, which you need to reduce fractions.
Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
