HESI A2 Math Practice Test 2023

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 calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 60 mph and time is 5 hours, we get Distance = 60 mph x 5 hours = 300 miles. Therefore, the correct answer is C. Option A is incorrect as it miscalculates the product of 60 x 5. Option B is incorrect as it is a lower value. Option D is a duplicate of option A and is also incorrect.

Correct Answer: B

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in 1 gram. Therefore, 7 grams x 1000 = 7000 milligrams, which corresponds to choice B. Choice A is incorrect as it represents 700 mg (not 7000 mg). Choice C is incorrect as it represents 70 mg (not 7000 mg). Choice D is incorrect as it represents 0.007 mg (not 7000 mg).

Correct Answer: A

Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3000 millimeters divided by 1000 equals 3 meters. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert millimeters to meters. Choice B is 30 times the correct answer, choice C is 10 times less, and choice D is 100 times more.

Correct Answer: D

Rationale: To convert 3/8 to a decimal, divide the numerator (3) by the denominator (8): 3 ÷ 8 = 0.375. The correct answer is D. Choice A (0.25) is the decimal equivalent of 1/4, not 3/8. Choice B is a duplicate of A. Choice C (0.3) is the decimal equivalent of 3/10, not 3/8.
