HESI A2 Math Practice Test 2023

Correct Answer: D

Rationale: To find the total number of pages the man reads per day, we multiply 2 chapters/day by 6 pages/chapter, which equals 12 pages/day. To determine how many days it will take to finish a 798-page book at 12 pages/day, we divide 798 by 12, resulting in approximately 66.5 days. This is why choice D is correct. Choice A (133 days) is incorrect because it overestimates the time needed, while choice B (399 days) and choice C (75 days) underestimate the time required to finish the book.

Correct Answer: B

Rationale: To determine the number of nurses needed for 40 patients: 1. Calculate the nurse-to-patient ratio: 5 nurses for 20 patients = 1 nurse for 4 patients. 2. Divide 40 patients by the ratio (40 patients ÷ 4 patients/nurse) = 10 nurses. Therefore, 10 nurses are needed for 40 patients. Choice B (8) is incorrect as it does not align with the calculated ratio. Choices A (7) and C (9) are also incorrect as they do not account for the correct calculation based on the given ratio.

Correct Answer: A

Rationale: To solve for x in the proportion 120:x = 40:0.5, first cross multiply to get 120*0.5 = 40*x. This simplifies to 60 = 40x. Divide both sides by 40 to find x = 1.5, which is choice A. The other choices are incorrect because: - B: 60 - Incorrect, doesn't match the calculation. - C: 0.167 - Incorrect, not the result of the calculation. - D: 16 - Incorrect, doesn't match the calculation.

Correct Answer: B

Rationale: To convert kilograms to pounds, you multiply by 2.2. In this case, 75 kg x 2.2 = 165 pounds. Therefore, the correct answer is B: 150 pounds. Choice A is incorrect as it is less than the actual conversion. Choices C and D are also incorrect as they are significantly lower than the correct conversion.

Correct Answer: A

Rationale: To subtract 32 divided by 8\9, first divide 32 by 8 to get 4. Then divide 4 by 9, which equals 4\9. Subtracting 4\9 from 32 gives 36, which is the correct answer (A). Choice B (32) is incorrect as it only divides 32 by 8, not considering the second division by 9. Choices C (40) and D (44) are incorrect as they do not follow the correct division and subtraction steps.
