HESI A2 Practice Test Math

Correct Answer: D

Rationale: To determine if a number is divisible by another, it must leave no remainder when divided. 7 is a prime number and can only be divided by 1 and itself (7). So, choices A and B are incorrect. Since 7 is a prime number, it is only divisible by numbers that are factors of 7 (1, 7) or itself. Therefore, choice C is also incorrect. The correct answer is D because 7 can be evenly divided by 2, 3, and 7 without any remainder, making it divisible by these numbers.

Correct Answer: A

Rationale: To find the number of plots, divide the total land by the size of each plot: 56 acres ÷ 0.25 acres/plot = 224 plots (Option A). This is correct as it follows the basic concept of division. Option B, C, and D are incorrect as they do not result from the correct division calculation.

Correct Answer: B

Rationale: To find 20% of 150, you multiply 150 by 20% (or 0.20). So, 150 * 0.20 = 30. Therefore, the correct answer is B (30). Choice A (25) is incorrect because 20% of 150 is not 25. Choice C (35) is incorrect because it is more than 20% of 150. Choice D (20) is incorrect because 20% of 150 is not the same as the original number 150.

Correct Answer: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.
