HESI A2 Math Practice Test 2023

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 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.

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

Correct Answer: A

Rationale: To convert the infant's weight from grams to pounds, divide 3,459 by 453.59 to get approximately 7.63 pounds. Since 1 pound is equal to 16 ounces, multiply the decimal part (.63) by 16 to get 10.08 ounces. Therefore, the infant's weight is 7 pounds and 10 ounces, making choice A the correct answer. Choices B, C, and D are incorrect due to incorrect conversions or calculations. B and C have the pound and ounce values switched, and D incorrectly converts the weight to 3 pounds and 13 ounces.
