HESI A2 Practice Test Math Questions

Question 1 of 5

If 30% of a given number is 18, what is the full number?

Correct Answer: A

Rationale: To find the full number, we can set up the equation: 0.30x = 18, where x is the full number. Solving for x, we get x = 18 / 0.30 = 60. Therefore, the correct answer is A (60). Choice B (30): 0.30 of 30 is 9, not 18. Choice C (40): 0.30 of 40 is 12, not 18. Choice D (45): 0.30 of 45 is 13.5, not 18.

Question 2 of 5

A patient needs to increase his calcium intake. If each tablet contains 500 mg of calcium and the patient needs to take 1,500 mg per day, how many tablets should the patient take?

Correct Answer: A

Rationale: The correct answer is A: 3 tablets. To reach the daily intake of 1,500 mg of calcium, the patient should take 1,500 mg ÷ 500 mg per tablet = 3 tablets. Taking 3 tablets will provide the required 1,500 mg of calcium. Choice B (4 tablets) would exceed the required amount, choice C (2 tablets) would be insufficient, and choice D (5 tablets) would exceed the required amount as well. Therefore, A (3 tablets) is the correct answer.

Question 3 of 5

How many ounces are in 8 & 1/4 pints?

Correct Answer: C

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, to find the number of ounces in 8 & 1/4 pints, we multiply 8 by 16 (128 oz) and add 1/4 of 16 (4 oz). This gives us a total of 132 ounces (128 + 4). Therefore, the correct answer is C (132 oz). Option A is incorrect as it is the result of miscalculating the conversion. Option B and D are incorrect as they do not account for the additional 1/4 pint.

Question 4 of 5

Which of the following is equivalent to 0.0009?

Correct Answer: C

Rationale: The correct answer is C: 0.09%. To convert 0.0009 to a percentage, you move the decimal point two places to the right, resulting in 0.09%. Option A (0.009%) is incorrect as it would be the equivalent of 0.00009. Option B (0.9%) is incorrect as it represents 0.009. Option D (9%) is incorrect as it is equivalent to 0.09, which is 100 times greater than the given value.

Question 5 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 2 quarts of water.' The aide has a measuring device marked in liters. How many liters of water should be used?

Correct Answer: A

Rationale: The correct answer is A: 2 liters. 1 quart is equivalent to 0.946 liters. Therefore, 2 quarts equal 1.892 liters, which can be rounded to 2 liters for practical purposes. This conversion is necessary as the measuring device is marked in liters, and the directions in quarts need to be converted accurately. The other choices are incorrect because B (1 liter) is less than the required amount, C (3 liters) is too much, and D (5 liters) is excessive based on the conversion from quarts to liters.
