1. Fractions & Mixed Numbers (Adding & Subtracting)

2. Intro to Fractions
Remember fractions are parts of a whole

3. #10 Adding & Subtracting Fractions with like & unlike denominators
How do you add fractions with like (same denominators?
Keep the denominator and add the numerators together
Remember to reduce fractions to lowest terms
Example:

4. #10 Adding & Subtracting Fractions with like & unlike denominators
How do you add fractions with unlike (different) denominators
First you must find a common denominator
Either multiply both denominators and reduce or find the lowest common denominator (LCD)
Then, add numerators across & keep the common denominator
Example

5. #10 Adding & Subtracting Fractions with like & unlike denominators
What is an improper fraction?
When the numerator is larger than the denominator
Example:

6. #10 Adding & Subtracting Fractions with like & unlike denominators
How do you add mixed numbers?
Change mixed number into improper fraction (see prior slide)
Get your common denominator
Add numerators across & keep denominator
Example:

How do you subtract fractions with like denominators?
Subtract numerators and keep denominator
Example
