# How to Add Fractions

Simplify your life, and your fractions, by following these steps.

### Instructions

- Step 1:
**Add fractions with the same denominator**Add fractions that have the same bottom number, or denominator. Add the top numbers, or numerators, together, and keep the denominator the same. - Step 2:
**Find common denominator**When you are adding fractions with different denominators, find a denominator that is common to both fractions. To change a denominator without changing the value of the fraction, multiply the top and the bottom numbers by the same number. - TIP: For instance, to add the fractions 3/4 and 5/12, multiply both numbers in 3/4 by three to get 9/12.
- Step 3:
**Add numerators**Add the numerators together, and keep the denominators the same. For example, add 9/12 and 5/12 by adding the numerators – nine and five – to get 14/12. - Step 4:
**Simplify**Simplify the solution by dividing the numerator and denominator by the same number to make the lowest possible fraction. For example, the fraction 14/12 can be simplified by dividing both numbers by two for the answer 7/6, which can also be written as 1 1/6. - FACT: Fractions have been used throughout the last 2,000 years.
