How do you multiply fractions?

• A. Multiply numerators and multiply denominators
• B. Find a common denominator, then multiply
• C. Cross-multiply
• D. Subtract the numerators

Answer: (A)

To multiply fractions, multiply the top numbers together and multiply the bottom numbers together. In formula form, (a/b) × (c/d) = (ac) / (bd). After multiplying, you can simplify by canceling common factors if possible. For example, (2/3) × (4/5) = (2×4)/(3×5) = 8/15, which is already in simplest form. You can often reduce earlier by crossing factors before multiplying, like (3/4) × (8/9) → cancel 3 with 9 to get (1/4) × (8/3) = 8/12 = 2/3. The other methods—finding a common denominator, cross-multiplying, or subtracting numerators—are not used for multiplying fractions; they apply to addition/subtraction or solving proportions.
