Correct Answer: D

Rationale: To convert ounces to pounds, we know that 1 pound is equal to 16 ounces. Therefore, to find how many pounds are in 144 ounces, we divide 144 by 16, which equals 9 pounds. The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds. C: 8 pounds - Incorrect, as 144 ounces do not equate to 8 pounds.

Correct Answer: A

Rationale: To convert yards to inches, we know that 1 yard is equal to 36 inches. Therefore, 1.5 yards would be 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Option B, 60 inches, is incorrect because it does not accurately convert 1.5 yards to inches. Option C, 72 inches, and option D, 84 inches, are also incorrect as they do not correctly represent the conversion from yards to inches in this scenario.

The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds.

Correct Answer: A

Rationale: To add fractions, we need a common denominator, which for 3, 6, and 5 is 30. So, we rewrite the fractions with a denominator of 30: 20/30 + 5/30 + 12/30 = 37/30. Simplifying 37/30 as 1 & 7/30 gives us the correct answer, choice A. The other choices are incorrect because they do not reflect the accurate sum of the fractions. Choice B is incorrect as it simplifies to 1 & 1/15, not 1 & 7/30. Choice C simplifies to 2/5, which is not the sum of the given fractions. Choice D simplifies to 3/4, which is also not the sum of the fractions provided.

Correct Answer: B

Rationale: To find 80% of 55, you multiply 55 by 0.8 (which is the decimal equivalent of 80%). So, 55 * 0.8 = 44. Therefore, the correct answer is B (44). Choice A (40) is incorrect as it represents 80% of 50, not 55. Choices C (39) and D (45) are also incorrect calculations.
