Convert them to improper fractions, find a common denominator and proceed.
It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
To find the average of fractions, you first need to find a common denominator for all the fractions. Once you have the fractions with the same denominator, add them together to find the total. Then, divide the total by the number of fractions you added together to find the average. Remember to simplify the fraction if possible.
Well, darling, the common denominator for 1/3 and 4/9 is 9. You see, to add or subtract fractions, you need a common denominator, and in this case, multiplying 3 by 3 gives you 9. So, there you have it, simple math for a simple question.
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
