They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
No.
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
you find the common denominator
That's a "common" denominator. "Common" means "same for both" or "same for all".
A "common denominator"

That's a common denominator.
Common denominator
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.
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.
No.
Two or more numbers are needed to find their lowest common denominator which is the same as their lowest common multiple.
They are called like or similar fractions.
