Multiply: 4/9 x 4/5
Correct answer
B
Rationale
To multiply fractions, you simply multiply the numerators together and the denominators together. For 4/9 x 4/5, it would be (4 x 4) / (9 x 5) = 16/45. The correct answer is B.
Choice A (5/9) is incorrect as it results from multiplying the numerators and denominators in the wrong order.
Choice C (1/2) is incorrect because multiplying 4/9 and 4/5 does not yield 1/2.
Choice D (5/4) is incorrect as it results from adding the numerators instead of multiplying them.
Therefore, the correct answer is B (16/45) as it follows the correct multiplication process for fractions.
