TEAS Math Questions

Correct Answer: B

Rationale: To solve the expression, follow the order of operations (PEMDAS). First, multiply 2 by 8 to get 16. Then, add -3 and 16 to get 13. Finally, add 3 to 13 to get 16. Therefore, the correct answer is 13. Choice A (11) is incorrect because it does not account for the correct order of operations. Choice C (28) is incorrect as it only considers the addition of -3 and 3. Choice D (80) is incorrect as it wrongly multiplies 2 by 8 before adding -3.

Correct Answer: C

Rationale: To find the number of students who will complete the nursing program: 1. Out of 100 students, 3/4 major in nursing = 75 students. 2. Only 1/3 of those who major in nursing complete the program: (1/3) * 75 = 25 students. Therefore, the correct answer is C (25 students) because only a third of the 75 nursing majors, which is 25 students, will complete the nursing program. Choice A (75) is incorrect because it represents the total number of students majoring in nursing, not completing the program. Choice B (20) and Choice D (5) are incorrect as they do not consider the proportions given in the question and do not calculate the number of students completing the program accurately.

Correct Answer: C

Rationale: To determine which group is the smallest, we need to compare the fractions representing the proportion of patients in each group. Group Alpha has 1/2, Group Beta has 1/3, and Group Gamma has 1/6 of the total patients. To find the smallest group, we look for the smallest fraction. Among the choices, 1/6 in Group Gamma is the smallest fraction, hence Group Gamma is the smallest group. Incorrect choices: A: Group Alpha - 1/2 is larger than 1/3 and 1/6, making it larger than Group Beta and Group Gamma. B: Group Beta - 1/3 is larger than 1/6 but smaller than 1/2, making it larger than Group Gamma. D: Group Delta - This is not a valid choice in the question, so it is incorrect.

Correct Answer: A

Rationale: To calculate how many liters are left after using 25%, we first find 25% of 10 liters: 10 * 0.25 = 2.5 liters used. Subtracting this from the initial amount gives us the remaining water: 10 - 2.5 = 7.5 liters left. Therefore, choice A (7.5 liters) is correct. Choice B (8 liters) is incorrect because it doesn't account for the water that was used. Choice C (6.5 liters) and choice D (8.5 liters) are also incorrect as they do not reflect the correct calculation based on the given information.

Correct Answer: C

Rationale: To find the number of male patients who were not overweight as children, we first calculate the total number of male patients. Since 70% of the patients were women, 30% were men. This means there were 30 men in the study. Out of these men, 10% were overweight as children, which is 10% of 30, equaling 3 men. Therefore, the remaining men who were not overweight would be 30 - 3 = 27. Therefore, choice C (27) is the correct answer. Choices A, B, and D are incorrect as they do not accurately represent the calculation based on the given information.
