The common denominator of any two or more whole numbers, such as 5 6 and 8, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
24 and 48 are two possible common denominators for 3/8 and 5/6.
8/9, 5/12, 6/7
The Least Common Multiple (LCM) for 6 8 9 is 72.
To add fractions with the same denominators, simply add together the numerators, and cancel down if necessary. For example, 5/8 + 1/8 = 6/8. Cancelling this down to an improper fraction in its simplest form, this is equal to 3/4.
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
24 and 48 are two possible common denominators for 3/8 and 5/6.
8/9, 5/12, 6/7
The least common denominator for fractions with those denominators (11, 8 and 6) is 264.
The Least Common Multiple (LCM) for 6 8 9 is 72.

The least common denominator is 144. Other common denominators would be multiples of 144. If that's 1/2, 1/6 and 1/8, the LCD is 24.
Change them so they have like denominators. Multiply all that fractions by the least common denominator so that they'll have the same denominators. Example: 1/2 - 1/3 Step 1: The least common denominator is 6. Step 2: Change each fraction so their denominator is 6 (You'll get 3/6 and 2/6) Step 3: Subtract them: 3/6 - 2/6 = 1/6
The LCD is 40.
To add two fractions, you must first convert them to a common denominator, which is the Least Common Multiple of the denominators of the two fractions you're adding. For example, to add 5/6 and 1/8, you convert them to the common denominator LCM(6,8)=24. Then 5/6=20/24 and 1/8=3/24 so the sum is 23/24. To multiply two fractions, you multiply the numerators together and multiply the denominators together. Thus, 5/6 * 1/8 = (5*1)/(6*8) = 5/48. If both fractions are between 0 and 1, then the sum will always be greater than the product.
Greatest common denominators are infinite. The GCF is 8. The LCD is 840.
