You can either simplify then add or add then simplify your answer
Yes
Yes but they all must have the same common denominator
Because if there's no common denominator it'll be hard to simplify. And will cause you to get a headache.
because when we simplify fractions it will give you the correct answer and that is the rule.
The trick to adding fractions is three simple steps. First, make sure the bottom numbers (the denominators) are the same. Secondly, add the top numbers (the numerators), put the answer over the denominator. Finally, simplify the fraction if need be.
not always,only when you need to
When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.

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 different, find a common denominator, convert the fractions to equivalent fractions with the same denominator, proceed with adding the numerators, put that total over the denominator, simplify if possible. If the denominators are the same, skip the conversion, proceed with adding the numerators, put that total over the denominator, simplify if possible.
When you are trying to simplify fractions.
You need a common denominator for both.
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
