HESI A2 Practice Test Math

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.

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: 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.

Correct Answer: B

Rationale: To calculate the number of tablets needed, we divide the patient's weight by 30 (150/30 = 5). Then, we multiply the result by 2 since they need 2 tablets per 30 pounds (5 x 2 = 10). Therefore, the correct answer is B (10 tablets). Choice A is incorrect as it does not account for the weight calculation. Choices C and D are incorrect as they do not consider the dosage requirement based on the patient's weight.

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.
