HESI A2 Math Practice Test 2023

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.

Correct Answer: C

Rationale: To convert 9/10 to a decimal, you divide 9 by 10. The result is 0.9. This is because in decimal form, the denominator becomes the place value. So 9 divided by 10 equals 0.9. Choice A (0.7) is incorrect because 7/10 is equivalent to 0.7. Choice B (0.8) is incorrect because 8/10 is equivalent to 0.8. Choice D (1) is incorrect as 1 represents the whole number equivalent, not the decimal form of 9/10. Therefore, the correct answer is C (0.9).

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: A

Rationale: To convert yards to inches, we know that 1 yard is equal to 36 inches. Therefore, 1.5 yards would be 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Option B, 60 inches, is incorrect because it does not accurately convert 1.5 yards to inches. Option C, 72 inches, and option D, 84 inches, are also incorrect as they do not correctly represent the conversion from yards to inches in this scenario.

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.
