===The denominator of the first fraction is 3. The denominator of the second fraction is 5. Because these two numbers are different, we need the lowest common denominator, which, in this case is 15 because 3 x 5 = 15. So we multiply:===

**To Add Fractions with different denominators:**

 * ===**Find the Lowest Common Denominator (LCD) of the fractions**===
 * ===**Add in the new numbers to the fractions to have the LCD**===
 * ===**Add the numerators of the fractions**===
 * ===**Simplify the Fraction**===

**Example: Find the Sum of 2/9 and 3/12**

 * ===**Determine the Greatest Common Factor of 9 and 12 which is 3**===
 * ===**Either multiply the denominators and divide by the GCF (9*12=108, 108/3=36)**===
 * ===**OR - Divide one of the denominators by the GCF and multiply the answer by the other denominator (9/3=3, 3*12=36)**===
 * ===**Rename the fractions to use the Least Common Denominator(2/9=8/36, 3/12=9/36)**===
 * ===**The result is 8/36 + 9/36**===
 * ===**Add the numerators and put the sum over the LCD = 17/36**===
 * ===**Simplify the fraction if possible. In this case it is not possible**===

13 - 1 1/3 = ?
===In this situation, we may regard 13 as a mixed number without a fractional part. To convert it into a fraction, we look at the denominator of the fraction 4/3, which is 1 1/3 expressed as an improper fraction. The denominator is 3, and 13===

**Subtracting Fractions with Different Denominators**

 * To Subtract Fractions with different denominators:**
 * **Find the Lowest Common Denominator (LCD) of the fractions**
 * **Rename the fractions to have the LCD**
 * **Subtract the numerators of the fractions**
 * **The difference will be the numerator and the LCD will be the denominator of the answer.**
 * **Simplify the Fraction**
 * Example: Find the difference between 3/12 and 2/9.**
 * **Determine the Greatest Common Factor of 12 and 9 which is 3**
 * **Either multiply the numbers and divide by the GCF (9*12=108, 108/3=36)**
 * **OR - Divide one of the numbers by the GCF and multiply the answer times the other number (12/3=4, 9*4=36)**
 * **Rename the fractions to use the Lowest Common Denominator (3/12=9/36, 2/9=8/36)**
 * **The result is 9/36 - 8/36**
 * **Subtract the numerators and put the difference over the LCD = 1/36**
 * **Simplify the fraction if possible. In this case it is not possible**
