TEAS Test Sample Math Questions

Correct Answer: B

Rationale: To find the sum of 0.75 and 0.625, you add the two numbers together: 0.75 + 0.625 = 1.375. Therefore, the correct answer is B. Choice A (0.875) is incorrect because it is the sum of 0.75 and 0.125. Choice C (1.625) is incorrect because it is the sum of 0.75 and 0.875. Choice D (0.125) is incorrect as it is the sum of 0.75 and -0.625.

Correct Answer: A

Rationale: To divide fractions, we multiply the first fraction by the reciprocal of the second. So, (4/3) ÷ (9/13) = (4/3) x (13/9) = 52/27. The correct answer is A, 52/27, as it follows the correct procedure of dividing fractions. The other choices are incorrect because they do not result from the proper operation of dividing fractions.

Correct Answer: C

Rationale: To find what fraction the fourth person pays, we first calculate the sum of fractions paid by the first three people: 1/5 + 1/3 + 1/12 = 12/60 + 20/60 + 5/60 = 37/60. The total bill is 1, so the fourth person pays 1 - 37/60 = 23/60. Therefore, the correct answer is C (47/60). Choice A (1/4) is incorrect as it does not consider the fractions paid by the first three people. Choice B (13/60) is incorrect as it is the sum of the fractions paid by the first three people, not what the fourth person pays. Choice D (1/4) is a duplicate of choice A and is also incorrect.

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: 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.
