TEAS Math Practice Test

Correct Answer: D

Rationale: Correct Answer: D (1 apple) Rationale: 1. Xavier starts with 20 apples. 2. He gives half to Emma, leaving him with 10 apples. 3. He gives 6 apples to Jim, leaving him with 4 apples. 4. He uses 3/4 of his remaining 4 apples for the pie, leaving him with 1 apple. Summary: - Choice A (4 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie. - Choice B (6 apples) is incorrect because Xavier gives 6 apples to Jim. - Choice C (2 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie.

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 find 15% of 200, you multiply 200 by 0.15 (which is the decimal equivalent of 15%). 200 * 0.15 = 30. Therefore, the correct answer is A (30). Option B (20) is incorrect because it represents 10% of 200. Option C (25) is incorrect as it is not the result of calculating 15% of 200. Option D (40) is incorrect as it is the result of multiplying 20% by 200.

Correct Answer: B

Rationale: Correct Answer: B Rationale: To find 40% of N, you can multiply N by 0.4 (equivalent to 40/100). Therefore, the correct way is 0.4N. Option B (N/40) is incorrect because dividing N by 40 does not give 40% of N. Option A (0.4N) is correct. Option C (2/5 N) is equivalent to 40%. Option D (40N/100) simplifies to 0.4N, which is correct.

Correct Answer: C

Rationale: The correct answer is C because it presents a clear and testable hypothesis that directly links the amount of poison given to the speed of rat death. It follows the format of an appropriate hypothesis by stating a cause-and-effect relationship that can be tested through experimentation. A is incorrect because it lacks a specific hypothesis and does not propose a clear relationship between the amount of poison and rat death. B is incorrect as it poses a question rather than a hypothesis, and it does not establish a direct connection between the variables. D is incorrect because it is a general statement about poison and rats without proposing a specific hypothesis to test.
