HESI A2 Practice Test Math

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: B

Rationale: To determine the sign of the product when multiplying positive and negative integers, we follow the rule: Positive * Negative = Negative. This is because when we multiply a positive number by a negative number, the result will always be negative. Hence, choice B is correct. Choice A is incorrect because the product is not always positive. Choice C is incorrect as the sign of the product is consistent regardless of specific numbers used. Choice D is incorrect as positive and negative integers can indeed be multiplied.

Correct Answer: C

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, to find the number of ounces in 8 & 1/4 pints, we multiply 8 by 16 (128 oz) and add 1/4 of 16 (4 oz). This gives us a total of 132 ounces (128 + 4). Therefore, the correct answer is C (132 oz). Option A is incorrect as it is the result of miscalculating the conversion. Option B and D are incorrect as they do not account for the additional 1/4 pint.

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.

Correct Answer: D

Rationale: To find which percentage equals 1.25, we convert 1.25 to a percentage by multiplying it by 100. 1.25 * 100 = 125%. Therefore, the correct choice is D. Choice A (1250%) is incorrect as it represents 12.5, not 1.25. Choices B (25%) and C (50%) are also incorrect as they are significantly lower than 1.25.
