TEAS Math Practice Test

Correct Answer: B

Rationale: To convert 1.25 to a fraction, we note that the decimal has two decimal places. To convert it to a fraction, we write 1.25 as 125/100. Simplifying by dividing both numerator and denominator by 25, we get 5/4. Therefore, the correct answer is B: 5/4. A: 1 1/4 is the mixed number form of 5/4. C: 4/5 is the reciprocal of the correct answer. D: 25/20 is not simplified; it should be reduced to 5/4.

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.

Correct Answer: D

Rationale: To find the speed in feet per second, first convert 72 miles to feet (1 mile = 5280 feet). Then, convert 90 minutes to seconds (1 minute = 60 seconds). Next, divide the distance in feet by the time in seconds to get the speed in feet per second. The correct calculation is (72 miles * 5280 feet/mile) / (90 minutes * 60 seconds/minute) = 70.4 feet per second. Choice A is too low, choice B is too high, and choice C is extremely low compared to the correct answer.

Correct Answer: D

Rationale: To convert a decimal to a percentage, you multiply by 100. Therefore, 0.80 * 100 = 80%. So, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equal to 0.40. Choice B (125%) is incorrect as 0.80 is less than 1. Choice C (90%) is incorrect as 0.80 is not equal to 0.90.

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.
