1 Add / Subtract Mixed Numbers Adding 1. Get common denominator and make equivalent fractions 2. Add whole numbers as a group, fractions as a group 3. Reduce any improper fractions

2 Add / Subtract Mixed Numbers Adding 1. Get common denominator and make equivalent fractions 2. Add whole numbers as a group, fractions as a group 3. Reduce any improper fractions EXAMPLE :

3 Add / Subtract Mixed Numbers Adding 1. Get common denominator and make equivalent fractions 2. Add whole numbers as a group, fractions as a group 3. Reduce any improper fractions EXAMPLE : Common den = 6 Equivalent fractions

4 Add / Subtract Mixed Numbers Adding 1. Get common denominator and make equivalent fractions 2. Add whole numbers as a group, fractions as a group 3. Reduce any improper fractions EXAMPLE : Common den = 6 Equivalent fractions

5 Add / Subtract Mixed Numbers Adding 1. Get common denominator and make equivalent fractions 2. Add whole numbers as a group, fractions as a group 3. Reduce any improper fractions EXAMPLE :

6 Add / Subtract Mixed Numbers Subtracting 1. Get common denominator and make equivalent fractions 2. Borrow “1” if needed 3. Number – number, fraction – fraction 4. Reduce if needed

7 Add / Subtract Mixed Numbers Subtracting 1. Get common denominator and make equivalent fractions 2. Borrow “1” if needed 3. Number – number, fraction – fraction 4. Reduce if needed Borrowing “1” : When subtracting fractions, after getting a common denominator and making equivalent fractions, if the first numerator is smaller then the 2 nd numerator, you need to borrow. When borrowing using fractions you WILL ALWAYS borrow one in terms of your denominator.

10 Add / Subtract Mixed Numbers Subtracting 1. Get common denominator and make equivalent fractions 2. Borrow “1” if needed 3. Number – number, fraction – fraction 4. Reduce if needed Borrowing “1” : There is a shortcut to doing this… - subtract 1 from your whole number - add your numerator and denominator ( becomes the new numerator ) - keep your original denominator
