TEAS Math Practice Test

Correct Answer: B

Rationale: The median is the middle number when the numbers are arranged in ascending order. Step 1: Arrange the numbers in order: {2, 3, 9, 12, 15}. Step 2: The middle number in this set is 9, making it the median. Therefore, the correct answer is B: 9. Choice A (3) is incorrect as it is the smallest number in the set. Choices C (12) and D (15) are incorrect as they are greater than the median value of 9.

Correct Answer: A

Rationale: The correct answer is A: Multiplication. In the expression 8 + 5 * 3, multiplication should be completed first according to the order of operations (PEMDAS/BODMAS). Multiplication takes precedence over addition, so 5 * 3 should be calculated first, resulting in 15. Then, you can add 8 to 15 to get the final answer of 23. Summary: - Choice B: Addition should be done after multiplication in this expression. - Choice C: Division is not involved in the given expression. - Choice D: Subtraction is not applicable until after multiplication and addition are completed.

Correct Answer: C

Rationale: The number -4 is classified as real, rational, and integer. 1. Real: -4 is a real number as it exists on the number line. 2. Rational: -4 can be expressed as -4/1, which is a ratio of two integers. 3. Integer: -4 is a whole number that includes negative numbers. Therefore, the correct answer is C. Summary: A: Incorrect, as it includes "natural," which does not apply to negative numbers. B: Incorrect, as it includes "natural," which is only positive integers. D: Incorrect, as -4 is rational, not irrational.

Correct Answer: A

Rationale: To divide 52 by 27, we get 1 with a remainder of 25. Then, when we divide 51 by 27, we get 1 with a remainder of 24. Therefore, the correct answer is A: 52/27, as it represents the result of the division without simplification. Choices B, C, and D are incorrect as they do not accurately represent the division results obtained.

Correct Answer: C

Rationale: To find the sixth number, we can first calculate the sum of all six numbers by multiplying the average (6) by the total count (6), which equals 36. Since the sum of five numbers is 25, the sixth number can be found by subtracting 25 from 36, giving us 11 (Choice C). Other choices are incorrect because they do not satisfy the conditions given in the question. Choice A, 8, would make the sum of six numbers less than 36. Choice B, 10, would also make the sum less than 36. Choice D, 12, would make the sum greater than 36. Thus, the correct answer is C (11).
