HESI A2 Practice Test Math 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 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.
Question 2 of 5
What is 0.9 divided by 3?
Correct Answer: C
Rationale: To calculate 0.9 divided by 3, we divide 0.9 by 3, which equals 0.3. This is the correct answer (C) because dividing 0.9 by 3 results in 0.3. Option A (0) is incorrect as the division does not equal 0. Option B (3) is incorrect as the result is not equal to 3. Option D (9) is incorrect as the division does not equal 9. Therefore, the correct answer is C (0.3).
Question 3 of 5
What is the result of dividing 40.3 by 4.8?
Correct Answer: B
Rationale: To find the result of dividing 40.3 by 4.8, you divide 40.3 by 4.8 which equals approximately 8.4. The correct answer is B. To see why the other choices are incorrect: A: 7.5 - Incorrect, as it is not the result of 40.3 divided by 4.8. C: 6.2 - Incorrect, as it is not the result of 40.3 divided by 4.8. D: 9.1 - Incorrect, as it is not the result of 40.3 divided by 4.8.
Question 4 of 5
Convert the decimal 0.98 to a percent.
Correct Answer: A
Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.
Question 5 of 5
Which of these percentages equals 1.25?
Correct Answer: D
Rationale: To find which percentage equals 1.25, we convert 1.25 to a percentage by multiplying it by 100. 1.25 * 100 = 125%. Therefore, the correct choice is D. Choice A (1250%) is incorrect as it represents 12.5, not 1.25. Choices B (25%) and C (50%) are also incorrect as they are significantly lower than 1.25.
