To find the least common denominator, list the multiples of each denominator. The lowest one they have in common is the LCD.
For example:
2/3 and 3/4:
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 24...
The multiples of 4 are: 4, 8, 12, 16, 20, 24...
The common multiples are 12 and 24. Since 12 is the least, it is the LCM.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
To write equivalent fractions with the lowest common denominator, you first need to find the least common multiple (LCM) of the denominators of the fractions. Once you have the LCM, you can rewrite each fraction using that common denominator. This ensures that the fractions have the same denominator while maintaining their original values. Remember to simplify the fractions if needed to ensure they are in their lowest terms.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .
The least common denominator is 144.
To find the least common denominator of a set of unlike fractions, you first need to list the prime factors of each denominator. Then, identify the highest power of each prime factor that appears in any of the denominators. Finally, multiply these highest powers together to find the least common multiple, which will be the least common denominator for the fractions.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
The least common denominator of 9, 12, and 16 is 144.

you can find the least common denominator and then order them.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

to make your denominator common you have to times a number that equals the same
You need at least two fractions to find a common denominator.
