Step 1. Simplify brackets -1/2 + 5/9 Step 2. Find the Least Common Denominator (LCD) of 1/2, 5/9 LCD = 18 Step 3. Make the denominators the same as the LCD -1*9/2*9 + 5*2/9*2 Step 4. Simplify. Denominators are the same now. -9/18 + 10/18 Step 5. Join the denominators -9 + 10/18 Step 6. Simplify Answer = 1/18
