1. Chapter 6: Lesson 3: Adding and Subtracting Mixed Numbers
Objective: Learn to add and subtract mixed numbers.

2. To add and subtract mixed numbers:
Steps:
First add or subtract the fractions. (Follow the adding and subtracting fraction steps from lesson 6- 2.)
If the denominators are different, change the fractions making them equivalent by finding the common denominators (LCD).
Add or subtract the fractions, then the whole numbers.
Simplify if necessary.
5. If your answer is improper, rewrite
the answer as a proper mixed
number in simplest form.

3. Borrowing/Regrouping:
When subtracting fractions, if after you change the fractions using common denominators (LCD), the numerator in the first fraction is smaller than the numerator in the second fraction, you will have to borrow/regroup.
When borrowing you have to take one away from the whole number. Then the trick is to add the same amount (number) in the denominator to the numerator.
Then you may subtract normally.

5. Homework: Add or subtract each mixed number. Simply your answer.
