The common denominator of any two or more whole numbers, such as 10 12 18 and 20, 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.

How do you find the sum of 5 over 12 and 9 over 6?
5/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/12
How do you simplfiy fractions?
You find a common factor between numerator and denominator. Then, you divide numerator and denominator between this factor. Continue, until there are no more common factors. Here are some examples: 4/10 - common factor is 2: 4/10 = (4/2) / (10/2) = 2/5. 12/18 - common factor is 6: 12/18 = (12/6) / (18/6) = 2/3. You don't need to figure out the greatest common factor: 60/80 = 6/8 = 3/4 (first I divided numerator and denominator by 10, then I continued searching for further factors; finding the factor 2). (x3 + 3x2) / 5x - divide by the common factor x, with the result (x2 + 3x) / 5.
How do you add one third plus one sixth plus three eighteens?
two thirds. Here's how:You need to have a common denominator to add or subtract fractions. Most people choose the Least Common Denominator (or Lowest Common Denominator), but any denominator which has all of the denominators as factors will get you the correct answer as an equivalent fraction. Now with this one, you could first simplify 3/18 to 1/6, then proceed, or you can just look at the denominators first.Looking at the denominators you can just multiply them all together to get a common denominator of 324, or try to find a lower common denominator: 6 is a factor of 18, and 3 is a factor of 18, so 18 is the Lowest Common Denominator.We need to convert the other fractions to equivalent fractions with 18 as the denominator. So for 1/3: 18 ÷ 3 = 6, so multiply the numerator and denominator by 6, to get 6/18; and for 1/6: 18 ÷ 6 = 3, so multiply numerator and denominator by 3, to get 3/18.Now we have 6/18 + 3/18 + 3/18. Add the numerators: 6 + 3 + 3 = 12, and put this over 18: 12/18. Now simplify if you want: 6 is common to both 12 & 18, so you can cancel: 12/18 = (6 × 2)/(6 × 3) = 2/3.
