TEAS Math Practice Test

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

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 find the sum of 3/8 and 5/8, you add the numerators together which gives you 3 + 5 = 8. The denominator remains the same (8). So, the sum is 8/8 which simplifies to 1 whole. Therefore, the correct answer is A: 1. Choice B is incorrect as 1 1/4 is greater than 1. Choice C is incorrect as 01-Feb is not a valid fraction. Choice D is incorrect as 03-Apr is not a valid fraction.

Correct Answer: A

Rationale: To express 18/5 as a reduced mixed number, we divide 18 by 5 which equals 3 with a remainder of 3. So, 18/5 = 3 3/5. This mixed number is in its simplest form. Choice A is correct. Choices B, C, and D are incorrect as they do not represent the correct division of 18 by 5 resulting in the remainder of 3.

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.
