To add fractions, you have to find their common denominator by multiplying the two denominators together and one of the numerators to the others. Then you add just the top numbers together.

No only when adding or subtracting fractions a common denominator is needed
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

They have to have a common denominator
A common denominator is needed when adding or subtracting fractions of different denominators.
Yes.
A Common Denominator
Many places, but a common one is in adding fractions where we find a common denominator.
No, You only need a common denominator when adding or subtracting fractions.
You need a common denominator for both.
a common denominator
Find a common denominator and proceed.
