TEAS Math Practice Test

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: 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: To find what number 20 is equal to 40% of, you divide 20 by 0.40 (40%). This gives 50, which is choice A. The correct answer is A because 20 is indeed 40% of 50. Choices B, C, and D are incorrect because 20 is not 40% of 8, 200, or 5000 respectively.

Correct Answer: A

Rationale: To round 8.067 to the nearest tenth, we look at the hundredth place, which is 6. Since 6 is equal to or greater than 5, we round the digit in the tenths place up by 1. Therefore, 8.067 rounded to the nearest tenth is 8.1. Choice A is correct because it correctly follows the rounding rule. Choice B is incorrect as it is a duplicate of Choice A. Choice C is incorrect as it rounds down to the nearest whole number, not the nearest tenth. Choice D is incorrect as it rounds up to the hundredth place, not the nearest tenth.

Correct Answer: A

Rationale: The correct answer is A. The domain of a function is the set of all possible input values. For the function y = 1/x, the denominator cannot be 0 since division by zero is undefined. Therefore, x cannot be 0. Hence, the domain includes all real numbers except 0, which is choice A. Choices B, C, and D are incorrect because B restricts x to be greater than 0, C limits x to be exactly 0, and D fixes x to be 1, all of which are not applicable for the given function.
