Ordering Fractions

 

 

If denominators are the same, then we only need to compare the numerators, for example:

 

 

If the denominators are different, then we need to change the denominators to a common one by using equivalent fractions. For example, to compare:
First, we need to get the least common denominator - LCD (which is the LCM of the denominators) as follows:
Next, we find the equivalent fractions with the denominator 36:
           

Now we can compare and find that

 

 

The following video will show more examples of comparing fractions and ordering fractions.
