You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
No.
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
yes you should use a common denominator when subtracting with fractions, it makes it much easier.
No you do not.
You don't need a common denominator to divide fractions.

You don't need a common denominator to divide fractions.
you flip the last (second) fraction, and then you change the divide sign into a times sign. You can then times the fractions from there. You do not need the same denominator to times fractions.
No only when adding or subtracting fractions a common denominator is needed
