Math HESI A2 Practice Test Questions

Question 1 of 5

A teacher's aide is preparing a snack for the class. In order to prepare the powdered drink, the aide must convert the directions to metric. The directions say, 'Dilute contents of package in 3 quarts of water.' The aide has a measuring device marked in liters. How many liters of water should be used?

Correct Answer: B

Rationale: The correct answer is B (2.8 liters) because 1 quart is equivalent to 0.946 liters. Therefore, 3 quarts would be 3 * 0.946 = 2.838 liters, which is closest to 2.8 liters. Choice A (3.0 liters) is incorrect because it does not accurately convert quarts to liters. Choice C (2.5 liters) is incorrect as it underestimates the conversion. Choice D (3.5 liters) is incorrect as it overestimates the conversion. The most accurate conversion is 2.8 liters, making it the correct answer.

Question 2 of 5

Convert 5/8 to a decimal.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.

Question 3 of 5

What is the result of subtracting 4.7 from 9.5?

Correct Answer: A

Rationale: To find the result of subtracting 4.7 from 9.5, we need to subtract 4.7 from 9.5. This can be calculated as 9.5 - 4.7 = 4.8. Therefore, the correct answer is A. Choice B (4.9) is incorrect because it is not the result of the subtraction operation provided in the question. Choice C (4.6) is incorrect because it is the result of subtracting 5.1 from 9.7, not 4.7 from 9.5. Choice D (4.7) is incorrect because it is the number being subtracted and not the final result of the subtraction.

Question 4 of 5

If a runner runs 5 miles in 45 minutes, what is their average speed in miles per hour?

Correct Answer: A

Rationale: To calculate average speed, divide total distance by total time. In this case, 5 miles in 45 minutes equals 5/0.75 = 6.67 mph. Choice A is correct because it correctly calculates the average speed based on the given information. Choices B, C, and D are incorrect as they do not accurately calculate the average speed.

Question 5 of 5

How many milligrams are in 7 grams?

Correct Answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. So, 7 grams x 1000 = 7000 mg. Therefore, the correct answer is A: 7000 mg. Option B (7 mg) is incorrect because it represents the original unit (grams). Option C (700 mg) is incorrect as it is a partial conversion error. Option D (70 mg) is incorrect as it is a multiple of 10 error.
