HESI A2 Math Practice Test 2023 - Nurselytic

Correct Answer: A

Rationale: 1 meter is equal to 1000 millimeters.
Therefore, to convert 3000 millimeters to meters, we divide by 1000. 3000 millimeters / 1000 = 3 meters.
Choice A, '3 meters,' is the correct answer.
Choice B, '30 meters,' is incorrect because it represents a miscalculation of multiplying instead of dividing.
Choice C, '0.3 meters,' is incorrect as it is the result of a decimal error.
Choice D, '300 meters,' is incorrect as it is a result of not converting millimeters to meters correctly.

Correct Answer: C

Rationale:
To find the total number of chapters, divide the total number of pages by the number of pages per chapter: 798 · 6 = 133 chapters. Reading 2 chapters per day means it will take 133 · 2 = 66.5 days.
Choice A, 133 days, is incorrect because it miscalculates the days needed to finish the book.
Choice B, 399 days, is incorrect as it doesn't consider the number of chapters read per day.
Choice D, 75 days, is incorrect as it doesn't account for the total number of chapters in the book.

Correct Answer: C

Rationale:
To solve for x, cross-multiply: x/250 = 3/500. This simplifies to x = 1.5.
Therefore, the correct answer is 1.5.
Choice A (150) is incorrect because it does not account for the division by 250.
Choice B (25.5) is incorrect as it is not the correct result of the calculation.
Choice D (60) is incorrect as it is not the correct result of the calculation either.

Correct Answer: C

Rationale:
To convert 9/10 to a decimal, divide 9 by 10: 9 · 10 = 0.9. The correct answer is 0.9.
Choice A (0.7) is incorrect as 7/10 is equal to 0.7.
Choice B (0.8) is incorrect as 8/10 is equal to 0.8.
Choice D (1) is incorrect as 10/10 would be equal to 1.

Correct Answer: A

Rationale:
To add fractions, find a common denominator (30), which gives 20/30 + 5/30 + 12/30=37/30= 1 7/30
