Comparing and Ordering Fractions Common Denominators

Convert both fractions into equivalents with the same denominator by finding the lowest common multiple. Then focus on the numerators. This method works for...

• comparing, ordering, adding and subtracting fractions.

• comparing and ordering fractions only.

• adding and subtracting fractions only.

• Finding a fraction of an amount.
