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. Did You Know? Fractions have been used throughout the last 2,000 years.
