HESI A2 Practice Test Math

Correct Answer: B

Rationale: To find x in the equation 40:5 = 60:x, we first simplify the left side to 8. Then, we set up the equation 8 = 60:x. To solve for x, we isolate x by multiplying both sides by x/60, resulting in x = 60/8 = 7. Choice B is correct. Choices A, C, and D are incorrect because they do not yield the correct value when substituted back into the equation.

Correct Answer: A

Rationale: The correct answer is A: 33%. To find the percentage of male students, subtract the number of female students (32) from the total number of students (48) to get the number of male students (16). Then, divide the number of male students (16) by the total number of students (48) and multiply by 100 to get the percentage of male students, which is 33%. Choice B (66%) is incorrect because it represents the percentage of female students, not male students. Choice C (25%) and Choice D (45%) are also incorrect as they do not accurately reflect the percentage of male students in the class.

Correct Answer: A

Rationale: To find the full number, we can set up the equation: 0.30x = 18, where x is the full number. Solving for x, we get x = 18 / 0.30 = 60. Therefore, the correct answer is A (60). Choice B (30): 0.30 of 30 is 9, not 18. Choice C (40): 0.30 of 40 is 12, not 18. Choice D (45): 0.30 of 45 is 13.5, not 18.

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 find the result of dividing 40.3 by 4.8, you divide 40.3 by 4.8 which equals approximately 8.4. The correct answer is B. To see why the other choices are incorrect: A: 7.5 - Incorrect, as it is not the result of 40.3 divided by 4.8. C: 6.2 - Incorrect, as it is not the result of 40.3 divided by 4.8. D: 9.1 - Incorrect, as it is not the result of 40.3 divided by 4.8.
