TEAS Test Sample Math Questions

Correct Answer: B

Rationale: To calculate speed in feet per second, we need to convert miles to feet and minutes to seconds. 72 miles = 72 * 5280 feet. 90 minutes = 90 * 60 seconds. Speed = distance / time. So, speed = (72 * 5280) / (90 * 60) = 48.9 feet per second. Therefore, choice B is correct. Choice A is too slow, choice C is extremely slow, and choice D is too fast when compared to the calculated speed.

Correct Answer: B

Rationale: To add 1/6 and 1/2, find a common denominator which is 6. Then, 1/6 + 1/2 = (1/6) + (3/6) = 4/6. Simplifying 4/6 gives 2/3, which is the reduced form of the sum. Choice B is correct. Choices A, C, and D are incorrect because they do not represent the correct result of adding 1/6 and 1/2 in reduced form. Option A simplifies to 9/7, Option C simplifies to 31/36, and Option D simplifies to 3/5, none of which are the correct answer.

Correct Answer: C

Rationale: The product of two irrational numbers can be either rational or irrational. To understand this, consider √2 * √2 = 2, making it rational. However, √2 * π remains irrational. Therefore, the product can be either rational or irrational, leading to choice C being the correct answer. Choice A is incorrect because the product may be rational. Choice B is incorrect as the product is not always rational. Choice D is incorrect as it does not address the possibility of the product being rational.

Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: To write 0.80 as a percent, you multiply it by 100. So, 0.80 * 100 = 80%. Therefore, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as 0.80 is less than 100%. Choice C (90%) is incorrect because 0.80 is not equal to 90%.
