**6-1 Adding and Subtracting Fractions with __//LIKE//__ Denominators** **pg. 324**

Like Denominators: same bottom number of a fraction

***In order to add or subtract fractions, denominators MUST be the same!!!!!!!!!!!!!!**


 * Once denominators are the same, add/subtract numerators. **
 * Denominators STAY THE SAME. **
 * SIMPLIFY YOUR ANSWER **


 * Ex. **
 * __1__ + __2__ = __3__ **
 *  4 4 4 **

**6-2 Adding and Subtracting Fractions with //__UNLIKE__// Denominators**  **pg. 328**
