TEAS Test Practice Math

Correct Answer: B

Rationale: The correct answer is B (100 students passed the exam). Since all students who took the exam passed, if the class has 200 students, then all 200 students must have taken the exam, and all of them passed. Therefore, the total number of students who passed the exam is equal to the total number of students who took the exam, which is 200. So, the correct answer is 200 students passed the exam. Choices A, C, and D are incorrect because they do not reflect the fact that all students who took the exam passed.

Correct Answer: C

Rationale: To determine the number of prizes for fifth-grade students, we need to allocate the prizes proportionally based on the number of students in each grade. 1. Calculate the total number of students in the school: 35 (Grade 1) + 38 (Grade 2) + 38 (Grade 3) + 33 (Grade 4) + 36 (Grade 5) = 180 students. 2. Calculate the proportion of students in fifth grade: 36 (Grade 5 students) / 180 (total students) = 0.2 or 20%. 3. Apply this proportion to the total number of prizes (20 prizes): 20 (total prizes) * 0.2 = 4 prizes for fifth-grade students. Therefore, the correct answer is B: 4 prizes for fifth-grade students. Other choices are incorrect because they do not accurately reflect the proportional allocation based on the number of students in each grade.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Kyle wants to donate one-fifth of his $950 savings to 8 charities. 2. One-fifth of $950 is $190 ($950 / 5 = $190). 3. If he donates $30 to each charity, $30 x 8 charities = $240. 4. His estimate of donating $240 is more than $190 (one-fifth of $950). 5. Hence, the estimate is not reasonable as $240 exceeds one-fifth of his total savings.

Correct Answer: C

Rationale: To find the percentage of Dr. Lee's patients hospitalized after taking the antibiotic, we multiply the percentage of patients who developed an infection (30%) by the percentage of those hospitalized (5% of 30%): 30% * 5% = 1.5%. Therefore, 1.5% of all patients were hospitalized. The correct answer is C (15%). Summary: A (1.50%): This is incorrect because it miscalculates the percentage of patients hospitalized. B (5%): This is incorrect as it represents the percentage of patients that developed an infection and not those hospitalized. D (30%): This is incorrect as it represents the total percentage of patients developing an infection, not those hospitalized.

Correct Answer: B

Rationale: To determine the total liquid in the pot, we add the volume of chicken broth (4 containers x 410ml) to the volume of water (1 liter = 1000ml). Total liquid = (4 x 410) + 1000 = 1640 + 1000 = 2640ml = 2.64 liters. Therefore, the correct answer is B. Choice A is incorrect as it miscalculates the total liquid. Choice C and D are significantly higher than the correct answer, indicating an error in calculation.
