What is a Common Denominator? When the denominators of two or more fractions are the same, they are Common Denominators. Why is it Important? Before we can add or subtract fractions, the fractions need to have a common denominator. In other words the denominators must be the same. Making The Denominators the Same.

When fractions have the same denominator, we say they have common denominators. (e.g. 1/6 has a common denominator with 2/6.) Having common denominators makes things like comparing, adding, and subtracting fractions easier. One way to find a common denominator for two (or more!) fractions is to list the multiples of each denominator until we ...
Aug 3, 2023 · When the denominators of two or more fractions are same, they are the common denominators. For example, in the fractions ${\dfrac{2}{9}}$, ${\dfrac{5}{9}}$, and ${\dfrac{8}{9}}$, 9 is the common denominator.
A common denominator is a common multiple of the denominators of two or more fractions. For example, for the fractions and , 24 and 48 are two of the common denominators for denominators 8 and 12. The least common denominator is 24.
