Final answer:
To multiply fractions, multiply the numerators and denominators. The simplified result of 4/2 x 6/18 is 2/3.
Step-by-step explanation:
To multiply fractions, you multiply the numerators together and the denominators together. In this case, 4/2 x 6/18 becomes (4 x 6)/(2 x 18) = 24/36. Simplifying the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 12, gives us 2/3. Therefore, the correct answer is D. 2/3.
