HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.

Correct Answer: B

Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4 quarts, we multiply 4 (quarts) by 32 (ounces/quart), which equals 128 ounces. Thus, the correct answer is B: 128 ounces. A: 64 ounces - Incorrect, this is the equivalent of 2 quarts, not 4. C: 32 ounces - Incorrect, this is the equivalent of 1 quart, not 4. D: 16 ounces - Incorrect, this is half the amount of 1 quart, not 4.

Correct Answer: A

Rationale: To find 25% of 200, you multiply 200 by 0.25 (25% is equivalent to 0.25). So, 200 x 0.25 = 50. Therefore, the correct answer is A: 50. Choices B, C, and D are incorrect because: B: 60 - This is not correct as 25% of 200 is 50, not 60. C: 25 - This is incorrect as 25% of 200 is 50, not 25. D: 30 - This is also incorrect as 25% of 200 is 50, not 30.

Correct Answer: B

Rationale: To subtract 14.5 - 7.25, align the decimals and perform subtraction. Starting from the right, subtract 5 from 0 (borrow 1 from 4), giving 5. Then, subtract 2 from 4, giving 2. The correct answer is 7.25. Other choices are incorrect because they do not match the result obtained from the subtraction process. Choice A and C are too small, while choice D is too large.

Correct Answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, to convert 5 kilograms to grams, you would do: 5 kg x 1000 = 5000 grams. Choice C (5,000 grams) is the correct answer. Choice A (50,000 grams) and choice D (50,000 grams) are incorrect because they do not correctly convert the kilograms to grams. Choice B (500 grams) is incorrect because it represents the grams equivalent of 0.5 kilograms, not 5 kilograms.
