first u find a common denominator
yes you should use a common denominator when subtracting with fractions, it makes it much easier.
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
They have to have a common denominator
Just add the fractions, and divide by 2. Before adding, you have to convert to a common denominator; in this case, you can use "4" as the common denominator.Just add the fractions, and divide by 2.

A Common Denominator
No only when adding or subtracting fractions a common denominator is needed
A common denominator is needed when adding or subtracting fractions of different denominators.
You need a common denominator for both.
a common denominator
No, You only need a common denominator when adding or subtracting fractions.
A common denominator.
Adding and subtracting fractions.
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
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.
