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