Common denominators are multiples that are being used as denominators. The process to find them is the same.
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
A common denominator results from comparing two or more unlike denominators. It can be the same as one of the denominators, but doesn't have to be.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
Unit fractions all have the same numerators but the denominators can be different.
Common denominators are multiples that are being used as denominators. The process to find them is the same.
Least common multiples and lowest common denominators are essentially the same thing. Once the denominators are the same, it's easier to get the correct answer when adding and subtracting fractions.
Common factors go into the numbers, the numbers go into common multiples.
When subtracting or adding fractions the denominators must be the same if they are not then the LCM must be found.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
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.

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.
You have to make the fractions equivalent, which means you need to find the lowest common factor that goes into both the denominators.
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.
They are not different.
