Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put the answer over the denominator. Step 3: Simplify the fraction (if needed).

Write down the beginning fractions. Find a common denominator. Multiply both numbers on the first fraction by the bottom number of the second fraction. Multiply both numbers on the second fraction by the bottom number of the first fraction. Line both fractions up side by side with their new numbers.
