HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
The metric system of measurement was developed in France during Napoleon's reign. It is based on what multiplication factor?
Correct Answer: C
Rationale: The correct answer is C: 10. The metric system is based on multiples of 10, making conversions between units easy and logical. This factor allows for a systematic and uniform system of measurement, which is essential for scientific accuracy and global standardization. Choices A, B, and D are incorrect because the metric system is not based on the length of Napoleon's forearm, the number 2, or the atomic weight of helium. These options do not align with the foundational principles of the metric system, which is built on the decimal system for simplicity and consistency.
Question 2 of 5
A newborn weighs 3,459 grams. There are 453.59 grams per pound. What is the infant's weight in pounds and ounces?
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.
Question 3 of 5
A female ran a 24-mile course. Her first 6 miles took 1 hour, the second set of 6 miles took 1.2 hours, the third set of 6 miles took 1.5 hours, and the fourth set of 6 miles took 1.6 hours. How long did it take her to complete the course?
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.
Question 4 of 5
Convert 0.25 to a fraction.
Correct Answer: A
Rationale: To convert 0.25 to a fraction, recognize that 0.25 is equivalent to 25/100, which simplifies to 1/4 when both the numerator and denominator are divided by their greatest common factor, which is 25. Therefore, the correct answer is A: 1/4. Choice B (1/3) and Choice C (1/2) are incorrect because they do not equal 0.25. Choice D (3/4) is incorrect as it is the reverse of the correct answer.
Question 5 of 5
How many liters are in 300 milliliters?
Correct Answer: A
Rationale: To convert milliliters to liters, we need to divide by 1000 since there are 1000 milliliters in a liter. So, 300 milliliters ÷ 1000 = 0.3 liters. Therefore, the correct answer is A: 0.3 liters. Explanation for other choices: B: 3 liters - Incorrect, as 300 milliliters is not equal to 3 liters. C: 0.03 liters - Incorrect, the decimal point placement is off. D: 3.3 liters - Incorrect, as it is not the correct conversion from milliliters to liters.
