Subtracting Mixed Numbers

Use these steps for subtracting mixed numbers.
-  Convert mixed numbers into improper fractions.
-  Find equivalent fractions with the same denominator for unlike fractions. (fractions with different denominators) 
-  Subtract the second fraction from the first one. 
-  Write your answer in lowest terms.
-  If the answer is an improper fraction, convert it into a mixed number.

Examples:

Example 1.  Subtract.
Solution: Convert mixed numbers into fractions: and
These two fractions are “unlike” fractions. (they have different denominators). Find equivalent fractions with the same denominator. Use this formula:


Example 2.  Find the difference.
Solution: Convert mixed numbers into fractions: and
Then:
