**Adding and Subtracting Fractions**

A Journey into the wonderful world of fractions…

3
**Lowest Common Multiple**

Find the multiples of each number and the first one in common is the lowest common multiple. What is the LCM of 5 and 6? 6 – 6, 12, 18, 24, 30, 36, 42, 48 5 – 5, 10, 15, 20, 25, 30, 35, 40

4
**Lowest Common Multiple**

SAMPLE: Find the lowest common multiple of 3 and 8? 3 – 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 8 – 8, 16, 24, 32, 40, 48, 56

5
**Adding Fractions with Like Denominators**

When the denominators are the same, add the numerators and keep the denominator. Simplify if needed. 4 9 2 9 6 9 2 3 + = = 1 8 3 8 2 8 1 4 - + = - = -

6
**Adding Fractions with UNLIKE Denominators**

When the denominators are different, you must create equivalent fractions with like denominators to add. Simplify if needed. 3 4 9 12 = 2 3 8 12 = + 5 12 17 12 = 1

7
**Subtracting Fractions**

Subtracting Fractions with Like Denominators When the denominators are the same, subtract the numerators and keep the denominator. Simplify if needed. 7 9 _ 4 9 3 9 1 3 = = 5 8 _ 1 8 6 8 3 4 - = - = -

8
**Subtracting Fractions**

Subtracting Fractions with UNLIKE Denominators When the denominators are different, you must create equivalent fractions with like denominators to subtract. Simplify if needed. 3 4 9 12 = _ 2 3 8 12 = 1 12

9
