HESI A2 Math Practice Test 2023 Questions

Question 1 of 5

What factor is used to convert pounds to kilograms?

Correct Answer: B

Rationale: The correct answer is B (2.2). To convert pounds to kilograms, you need to divide the weight in pounds by 2.2. This is because 1 pound is approximately equal to 0.454 kilograms. Therefore, by dividing the weight in pounds by 2.2, you are essentially converting pounds to kilograms. Choice A (1.8) is incorrect because it is not the accurate conversion factor for pounds to kilograms. Choice C (2.5) is also incorrect as it is not the standard conversion factor. Choice D (2) is not correct either, as it does not accurately convert pounds to kilograms.

Question 2 of 5

What is the result of dividing 4 7/8 by 1 1/6?

Correct Answer: A

Rationale: To divide mixed numbers, convert them to improper fractions. 4 7/8 = (8*4 + 7)/8 = 39/8 and 1 1/6 = (6*1 + 1)/6 = 7/6. Then divide 39/8 by 7/6: (39/8) ÷ (7/6) = (39/8) * (6/7) = 234/56 = 4 5/28 (Choice A). The other choices are incorrect because they do not yield the correct result when following the correct steps for dividing mixed numbers.

Question 3 of 5

Change 0.004 to a ratio.

Correct Answer: A

Rationale: To change 0.004 to a ratio, we need to express it as a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct because it accurately represents the ratio of 0.004. Choices B, C, and D are incorrect because they do not accurately reflect the equivalent ratio for 0.004.

Question 4 of 5

A man is reading a book with 798 pages. If he reads 2 chapters a day and each chapter has 6 pages, how many days will it take him to finish the book?

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.

Question 5 of 5

Add 2\3 + 1\6 + 2\5.

Correct Answer: A

Rationale: To add fractions, we need a common denominator, which for 3, 6, and 5 is 30. So, we rewrite the fractions with a denominator of 30: 20/30 + 5/30 + 12/30 = 37/30. Simplifying 37/30 as 1 & 7/30 gives us the correct answer, choice A. The other choices are incorrect because they do not reflect the accurate sum of the fractions. Choice B is incorrect as it simplifies to 1 & 1/15, not 1 & 7/30. Choice C simplifies to 2/5, which is not the sum of the given fractions. Choice D simplifies to 3/4, which is also not the sum of the fractions provided.
