TEAS Practice Test Math

Correct Answer: A

Rationale: The correct answer is A because the least common multiple (LCM) is the smallest number that both numbers can be multiplied into and still be divisible by both original numbers without leaving a remainder. Simply put, it is the smallest common multiple of the two numbers. The least common factor, on the other hand, is not a standard mathematical term. Choices B, C, and D are incorrect because they inaccurately describe the concept of least common multiple and least common factor. B describes the largest number rather than the smallest, C confuses division and multiplication, and D incorrectly defines both the least common multiple and least common factor.

Correct Answer: C

Rationale: To convert a percentage to a decimal, you divide by 100. In this case, 87.5% divided by 100 is 0.875. Therefore, choice C, 0.875, is the correct decimal form of 87.5%. Choices A and B are incorrect as they do not represent the correct decimal value. Choice D, 8.75, is also incorrect as it is the decimal form of 875%.

Correct Answer: A

Rationale: To find the expression for the length of the rectangle in terms of x, we first note that the length is six less than two times the width. Therefore, the expression for the length would be 2x - 6. This is because the length is equal to 2 times the width (2x) minus 6. Therefore, option A (2x - 6) is the correct answer. Option B (6-2x) is incorrect because it represents the width minus 2 times the width, which is not the correct relationship. Option C (6x-2) is incorrect because it represents 6 times the width minus 2, which is not the correct relationship. Option D (3x-4) is incorrect because it represents 3 times the width minus 4, which does not match the given relationship between the length and the width.

Correct Answer: A

Rationale: To convert yards to feet, you multiply by 3 because there are 3 feet in 1 yard. To convert feet to yards, you divide by 3. So, the correct answer is A. For the other choices, B, C, and D, the conversion factors are incorrect and do not match the actual relationship between yards and feet. B and D have incorrect multiplication factors, while C has an incorrect multiplication factor and division factor.
