How to subtract mixed numbers with unlike denominators & regrouping?

Step 1: Subtract the fractions.
If the denominators of the fractions are different then you need to convert the fractions to equivalent fractions with a common denominator. Check here if you need to review how to do that.
If the numerator of the first fraction is less than the numerator of the second fraction then you need to regroup the first fraction.
Subtract (or borrow) 1 from the whole number portion of the first fraction.
Convert the 1 into an equivalent fraction with the same denominator as the given fraction.
Add the equivalent fraction to the first fraction.
Now subtract the two fractions.
Step 2: Subtract the whole numbers.
Step 3: Add the results from step 1 and step 2 to get the final answer.

For example:
5 1/2 - 2 2/3
Step 1: Subtract the fractions.
Since the denominators of the fractions are different, you need to convert to equivalent fractions with a common denominator.
1/2 = 3/6
2/6 = 4/6
Since the first fraction is less than the second fraction, you need to regroup the first fraction.
Subtract 1 from 5 to get 4.
Convert the 1 to 6/6 and add to the first fraction.
6/6 + 3/6 = 9/6
Subtract the fractions: 9/6 - 4/6 = 5/6
Step 2: Subtract the whole numbers.
4 - 2 = 2
Step 3: The answer is then 2 5/6.
