Are there any questions? OPPORTUNITY FOR QUESTIONS: 1. QUESTIONS FROM THE CLASS 2. QUESTIONS TO THE CLASS: Q. What must be done to add fractions with different denominators? A. Find common denominators for both fractions, add the numerators, and keep the denominators. Now that we understand the process of adding fractions, let’s move on to subtracting fractions.
