Math HESI A2 Practice Test

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 8 1/4 pints can be calculated as 8 x 16 + 4 = 132 ounces. This is why choice B (132 oz) is correct. Choices A, C, and D are incorrect because they do not accurately represent the conversion of pints to ounces in this scenario.

Correct Answer: B

Rationale: To convert 1/5 to a decimal, you divide 1 by 5. This gives you 0.2, which is the correct answer (B). Choice A (0.5) is the decimal equivalent of 1/2, not 1/5. Choice C (1.5) is the sum of 1 and 1/2. Choice D (0.15) is the decimal equivalent of 15/100, not 1/5. Therefore, the correct answer is B (0.2).

Correct Answer: A

Rationale: To convert ounces to pounds, you divide the number of ounces by 16 since there are 16 ounces in a pound. Therefore, 160 ounces / 16 = 10 pounds. Choice A (10 pounds) is correct. Choices B, C, and D are incorrect because they do not correctly convert 160 ounces to pounds. Choice B is 8 pounds (160/16=10), Choice C is 5 pounds (160/16=10), and Choice D is 12 pounds (160/16=10).

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.

Correct Answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart equals 32 ounces. Therefore, 1.5 quarts would be 1.5 x 32 = 48 ounces. So, the correct answer is C (48 ounces). Choice A is incorrect as it incorrectly converts quarts to ounces. Choice B is half of the correct conversion. Choice D is double the correct conversion.
