HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: The correct answer is B (2.2). To convert pounds to kilograms, you need to divide the weight in pounds by 2.2. This is because 1 pound is approximately equal to 0.454 kilograms. Therefore, by dividing the weight in pounds by 2.2, you are essentially converting pounds to kilograms. Choice A (1.8) is incorrect because it is not the accurate conversion factor for pounds to kilograms. Choice C (2.5) is also incorrect as it is not the standard conversion factor. Choice D (2) is not correct either, as it does not accurately convert pounds to kilograms.

Correct Answer: D

Rationale: To find 70% of 200, you multiply 200 by 0.70 (70%). So, 200 x 0.70 = 140. Therefore, the correct answer is D (140). Choice A (100) and B (100) are incorrect as they do not represent 70% of 200. Choice C (200) is incorrect as it represents the full 100% of 200, not 70%.

Correct Answer: A

Rationale: To find 25% of 200, you multiply 200 by 0.25 (25% is equivalent to 0.25). So, 200 x 0.25 = 50. Therefore, the correct answer is A: 50. Choices B, C, and D are incorrect because: B: 60 - This is not correct as 25% of 200 is 50, not 60. C: 25 - This is incorrect as 25% of 200 is 50, not 25. D: 30 - This is also incorrect as 25% of 200 is 50, not 30.

Correct Answer: B

Rationale: To subtract mixed numbers, first convert them to improper fractions: 17 2\3 = 53\3 and 8 5\9 = 77\9. Then, find a common denominator, which is 9. Subtracting, you get 53\3 - 77\9 = (53*3 - 77)/9 = (159 - 77)/9 = 82/9. Convert 82/9 back to a mixed number, which is 9 1\9 (choice B). The other choices are incorrect because they do not match the correct result obtained through proper subtraction and conversion. Choice A is incorrect as it does not match the calculated result of 9 1\9. Choice C is incorrect as it does not match the calculated result of 9 1\9. Choice D is incorrect as it duplicates choice A without consideration of the actual calculation.

Correct Answer: A

Rationale: To convert yards to inches, you need to know that 1 yard is equal to 36 inches. Therefore, 1.5 yards is 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Choice B (60 inches) is incorrect because it does not accurately convert 1.5 yards to inches. Choices C (72 inches) and D (84 inches) are also incorrect as they do not reflect the correct conversion.
