You can find a common denominator of any set of denominators by multiplying them together. That result will not necessarily be the lowest common denominator. Example: 1/6 and 1/9 6 x 9 = 54 and 54 is a common denominator of 6 and 9, but the LCD is 18.
LCD(9, 6) = 18
9 is the common denominator. 2/3 = 6/9.
what is a common denominator for 6, 9 and 3

To add or subtract fractions, you need a common denominator. In this case, the common denominator for 1/3 and 4/9 is 9. To find a common denominator, you can identify the least common multiple of the denominators, which is 9 in this case. By rewriting 1/3 as 3/9, you can now add the fractions: 3/9 + 4/9 = 7/9.
The lowest common denominator of 6 and 9 is three.
If that's 6/4 and 9/5, the least common denominator is 20.
I am assuming you mean 8/9ths 4/6ths or 1/3rd if that is the case, 1/3rd is the smallest, followed by 4/6ths and then 8/9ths. First convert to common denominator, which is 9. 8/9 = 8/9 4/6 = 6/9 1/3 = 3/9 Now compare the numerators in the common denominator fractions. The common denominator fraction with the smallest numerator is the smallest. The smallest is 3/9; so 1/3 is the smallest fraction.
