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 round 847.89632 to the nearest hundredth, we look at the digit in the thousandth place, which is 6. Since 6 is greater than or equal to 5, we round up the digit in the hundredth place (9) by 1, making it 10. Therefore, the number becomes 847.90 (answer A). Choice B (900) is incorrect as it rounds to the nearest whole number. Choice C (847.89) is incorrect as it rounds down. Choice D (847.896) is incorrect as it does not round to the nearest hundredth.

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: A

Rationale: Step-by-step rationale: 1. Convert 1/3 to a decimal: 1 divided by 3 equals 0.3333... 2. Compare 0.5 to 0.3333...; it is evident that 0.5 is larger. 3. Therefore, 0.5 is larger than 1/3. Summary: Choice A is correct as 0.5 is greater than 1/3. Choice B is incorrect as 1/3 is smaller. Choice C is incorrect as they are not equal. Choice D is incorrect as a comparison can be made.

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.
