HESI A2 Practice Test Math

Correct Answer: A

Rationale: To add 1/2 + 4/5, we need a common denominator, which is 10 in this case. 1/2 becomes 5/10 and 4/5 remains as 4/5. Adding them gives 9/10. Converting 9/10 to a mixed number, we get 1 3/10, which is choice A. Choices B, C, and D are incorrect as they do not correctly represent the sum of the fractions.

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.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.

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: A

Rationale: To find x, first, find the ratio between the two parts of the equation: 7/5 = 91/x. Cross multiply to solve for x: 7x = 455. Divide by 7 to get x = 65 (Choice A). Choices B, C, and D are incorrect as they do not match the calculated value of x.
