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.
Common Denominator: Definition. A common denominator of two or more fractions is the shared multiple of their denominators. Example: The common denominators of $\frac{2}{3}$ and $\frac{5}{7}$ are 21, 42, 63, 84, etc. It means that both the fractions have equivalent fractions with denominators 21, 42, 63, 84, etc.
A common denominator is that in which the denominator i.e. the number below the fraction is the same throughout, thereby making your calculation process simpler. In case the two fractions do not have a common denominator, then you need to calculate the common denominator to get your answer.
When two or more fractions have the same denominator (the bottom number). We can add and subtract fractions only when they have a common denominator. To get common denominators we can multiply both top and bottom of a fraction by the same amount.
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.
