HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To convert 0.25 to a fraction, recognize that 0.25 is equivalent to 25/100, which simplifies to 1/4 when both the numerator and denominator are divided by their greatest common factor, which is 25. Therefore, the correct answer is A: 1/4. Choice B (1/3) and Choice C (1/2) are incorrect because they do not equal 0.25. Choice D (3/4) is incorrect as it is the reverse of the correct answer.

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 convert the infant's weight from grams to pounds, divide 3,459 by 453.59 to get approximately 7.63 pounds. Since 1 pound is equal to 16 ounces, multiply the decimal part (.63) by 16 to get 10.08 ounces. Therefore, the infant's weight is 7 pounds and 10 ounces, making choice A the correct answer. Choices B, C, and D are incorrect due to incorrect conversions or calculations. B and C have the pound and ounce values switched, and D incorrectly converts the weight to 3 pounds and 13 ounces.

Correct Answer: C

Rationale: To find the total number of pages in the book, we multiply the number of chapters by the number of pages per chapter: 2 chapters/day * 6 pages/chapter = 12 pages/day. To finish 798 pages, we divide 798 pages by 12 pages/day, giving 66.5 days. Therefore, the correct answer is C: 66.5 days. Choice A (133 days) is incorrect because it assumes the man reads 1 chapter per day instead of 2. Choice B (399 days) is incorrect as it overestimates the number of days needed by assuming the man reads only 1 page per day. Choice D (75 days) is incorrect because it underestimates the time needed by assuming the man reads 3 chapters per day instead of 2.

Correct Answer: B

Rationale: To find the sum of 1/3, 1/4, and 1/6, we need to first find a common denominator, which is 12 in this case. Then, we convert each fraction to have the same denominator: 1/3 = 4/12, 1/4 = 3/12, and 1/6 = 2/12. Adding these fractions gives us 4/12 + 3/12 + 2/12 = 9/12, which simplifies to 3/4 or 0.75. Therefore, the correct answer is B: 1/2. Explanation for other choices: A: 5/12 - Incorrect. This sum is not equal to the sum of 1/3, 1/4, and 1/6. C: 1/3 - Incorrect. This is the value of just one of the given fractions, not the sum of all three
