Correct answer: B. Multiply the numerators and multiply the denominators

2. Instead, the numerators are multiplied together to form the new numerator.
3. The denominators are multiplied together to form the new denominator.
4. Finding a common denominator or flipping the second fraction belongs to addition and division, not multiplication.
