Multiply the numerators of the two fractions. Since the numerators are both 2, you can multiply 2 * 2 to get 4. 3. Multiply the denominators of the two fractions. Since the denominators are both 4, just multiply 4 * 4 to get 16. Your answer is a fraction comprised of the new numerator and the new denominator.
