HESI A2 Math Practice Questions
Question 1 of 5
A teacher's aide must convert the directions from quarts to liters. The directions say to dilute the contents of a package in 3 quarts of water. How many liters should be used?
Correct Answer: A
Rationale: To convert 3 quarts to liters, we use the conversion factor 1 quart = 0.946 liters. So, 3 quarts x 0.946 = 2.838 liters, which is rounded to 2.8 liters. Therefore, the correct answer is A (2.8 liters). Option B (3.5 liters) is incorrect as it's not the accurate conversion. Option C (2.5 liters) is lower than the accurate conversion. Option D (4.0 liters) is higher than the accurate conversion.
Question 2 of 5
A worker in a warehouse ships 9 boxes each day. If every box must contain 3 shipping labels, how many shipping labels does the worker need each day?
Correct Answer: B
Rationale: To find the total number of shipping labels needed per day, we multiply the number of boxes by the number of labels per box: 9 boxes x 3 labels = 27 labels. This is why choice B (27 labels) is correct. Choice A (24 labels) results from multiplying the boxes by labels incorrectly. Choice C (20 labels) and choice D (30 labels) are both too low and too high respectively, indicating an incorrect understanding of the calculation required.
Question 3 of 5
What is the result of subtracting 8.4 from 3.7?
Correct Answer: D
Rationale: To subtract 8.4 from 3.7, we perform 3.7 - 8.4. First, subtract the whole numbers: 3 - 8 = -5. Then subtract the decimals: 0.7 - 0.4 = 0.3. Combine the results to get -5.3. Therefore, the correct answer is option D: 4.7. Option A (4.5) is the result of subtracting the whole numbers but not the decimals. Option B (4.8) and Option C (4.6) are incorrect as they do not result from the correct subtraction calculation.
Question 4 of 5
Solve: 8x = x^2.
Correct Answer: C
Rationale: To solve 8x = x^2, we rearrange the equation to x^2 - 8x = 0. Factoring gives x(x-8) = 0. So, x = 0 or x = 8. Therefore, the correct answer is C (16). Choices A, B, D are incorrect as they do not satisfy the equation x^2 = 8x.
Question 5 of 5
How many kilograms are in 4,000 grams?
Correct Answer: A
Rationale: To convert grams to kilograms, we need to divide by 1000 since there are 1000 grams in a kilogram. Thus, 4,000 grams divided by 1000 equals 4 kilograms. Therefore, the correct answer is A. Choice B is incorrect as it is not the result of the correct conversion. Choice C is incorrect as it represents the equivalent of 1000 grams, not 4000 grams. Choice D is incorrect as it is half of the correct conversion result.
