TEAS Math Questions

Correct Answer: C

Rationale: The correct order is Gamma, Alpha, Beta. Step 1: Find the least common multiple (LCM) of the fractions: LCM of 2, 3, and 6 is 6. Step 2: Calculate the number of patients in each group for a total of 6 patients. Group Alpha: 6 * (1/2) = 3 patients. Group Beta: 6 * (1/3) = 2 patients. Group Gamma: 6 * (1/6) = 1 patient. Therefore, the correct order is Gamma (1 patient), Alpha (3 patients), Beta (2 patients). Choice C is correct as it reflects this order. Choices A, B, and D are incorrect as they do not follow the correct distribution of patients based on the fractions given.

Correct Answer: A

Rationale: The correct answer is A: 3 hours. Since the car travels 60 miles in 1 hour, its speed is 60 miles per hour. To travel 180 miles at the same speed, it will take 180 miles / 60 miles per hour = 3 hours. Choice B, C, and D are incorrect because they do not accurately calculate the time required based on the given speed of the car. Choice B is too high, choice C is too low, and choice D is also too high.

Correct Answer: A

Rationale: To find the perimeter of a rectangle, you add all four sides. Given the width is 4 inches, and the length is 3 times the width (12 inches), the perimeter would be 2(4 + 12) = 2(16) = 32 inches. Therefore, the correct answer is A (28 inches). The other choices are incorrect because they do not match the calculated perimeter based on the given dimensions of the rectangle.

Correct Answer: B

Rationale: Step 1: Calculate the number of boys in the class. 60% of 30 students = 0.6 * 30 = 18 boys. Step 2: Calculate the number of girls in the class. Since there are 30 students in total, and 18 are boys, there must be 30 - 18 = 12 girls. Therefore, the correct answer is B: 12 girls. Other choices are incorrect because they do not align with the given percentages and total number of students.
