TEAS Practice Math Test

Correct Answer: A

Rationale: To calculate the percentage of Dr. Lee's patients hospitalized, we need to find 5% of the 30% who developed an infection. 5% of 30% is 1.5%. Therefore, the correct answer is A: 1.50%. Choice B (5%) is incorrect because it represents the percentage of patients who developed an infection, not those hospitalized. Choice C (15%) is incorrect as it is the total percentage of patients who developed an infection, not just those hospitalized. Choice D (30%) is incorrect as it represents the initial percentage of patients who developed an infection, not those hospitalized.

Correct Answer: D

Rationale: The correct answer is D: $144.65. To find the total cost of Susan's outfit, you need to add up the costs of the dress, shoes, and accessories. $69.99 (dress) + $39.99 (shoes) + $34.67 (accessories) = $144.65. This is the total cost of Susan's outfit. Explanation for incorrect choices: A: $69.99 - This is only the cost of the dress and does not include the shoes and accessories. B: $75.31 - This amount is not the total cost as it only includes the dress and shoes, excluding the accessories. C: $109.98 - This sum is the total of the dress and shoes but does not include the accessories. Therefore, the correct answer is D as it includes the combined cost of all items purchased.

Correct Answer: C

Rationale: To find the percentage of times Cora did not slip and fall, subtract the times she fell (20) from the total times around the rink (27): 27 - 20 = 7. Then, divide the times she did not fall (7) by the total times (27): 7 / 27 ≈ 0.259 or 26%. The correct answer is C (26%), as it represents the approximate percentage of times Cora did not slip and fall. Explanation for other choices: A: 37% - Incorrect. This percentage does not accurately represent the times Cora did not slip and fall. B: 74% - Incorrect. This percentage is too high and does not align with the calculation. D: 15% - Incorrect. This percentage is too low and does not align with the calculation.

Correct Answer: D

Rationale: To convert grams to milligrams, you need to multiply by 1000 because 1 gram = 1000 milligrams. Therefore, to find how many milligrams are in 5 grams, you would multiply 5 grams by 1000, resulting in 5000 milligrams. Option D is correct. Option A is incorrect as it represents a conversion from grams to micrograms, not milligrams. Option B is incorrect as it is a tenth of the correct answer. Option C is incorrect as it is only a hundredth of the correct answer.

Correct Answer: C

Rationale: To find the number of students who passed the exam, we first need to determine the total number of students who took the exam. Since half of the nursing students took the exam, the number of students who took the exam is 200/2 = 100. Then, three-fifths of those who took the exam passed, which is 3/5 * 100 = 60 students. Therefore, the correct answer is C (60). Choice A (120) is incorrect because it represents the total number of nursing students, not the number of students who passed the exam. Choice B (100) is incorrect because it represents the total number of students who took the exam, not the number who passed. Choice D (50) is incorrect because it does not consider the percentage of students who passed the exam.
