Learn what a common denominator is and how to find it using different methods. See how to use common denominators to add, subtract, compare and order fractions.
- The fractions with the common denominators are called the like fractions. For example: $\frac{2}{5}$ and $\frac{4}{5}$.
- No, the common denominators cannot be negative as it represents the common multiples of the denominators, which cannot be negative.
- Least Common Denominator is the smallest number that can be a common denominator of a set of fractions. On the other hand, the common denominator i...
Learn what a common denominator is and how to find it using the least common multiple or cross-multiplication methods. See examples of common denominators in real-life situations and practice problems with solutions.
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 ...
- At first i was confused by the option 15 because i wasn't thinking straight and thought that 15 was 10 times five instead of 10 plus five :)
- You would just keep listing all the multiples until you find a common one, so both 5 and 6 are multiples of 30, so the common denominator would be 30

- No, in this case 1/6 and 3/6 already have a common denominator of 6.
- 1∕4 + 11∕10 First, let's find the least common denominator. One way of doing this is to write down multiples of the smaller denominator until we ge...
- Usually multiple the denominators then cross multiply the denominators by the numerators.So if you have 4/6 x 5/8= what you would do is do 8 x 6 an...
- Reciprocals are fractions turned upside down and have the numerator in the denominator area with the denominator in the numerator area. For example...

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.
