When adding fractions, explain why it is better to find the lowest common denominator rather than any denominator that is common to the fractions. What is the easiest way to find the GCF and LCM? How do you list the following fractions from least to greatest: 12/15, 12/20, 48/30, 49...
Using LCM to Find an LCD The LCM of two or more numbers can be used when you are trying to add fractions with unlike denominators, such as 1/4 and 1/3. Adding fractions in this form requires you to find a common denominator, and rewrite each fraction to use that denominator b...

Purpose: LCM is used to find the smallest common denominator when adding or subtracting fractions, whereas GCF helps simplify fractions to their lowest terms. Method: To find LCM, we look for the least number common among the multiples, while for GCF, we search for the highest number common ...

When the denominators of two or more fractions are the same, they are Common Denominators.Why is it Important?Before we can add or subtract fractions, the fractions need to have a common denominatorIn other words the denominators must be the same....
Whenadding and subtracting fractions, common multiples are used to find acommon denominator. To keep the fractions from getting too large, the least common multiple is most often used. Either the least common multiple or another common multiple can be used. Let's take a look at both of these...
