TEAS Practice Test Math

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: The correct answer is C because a composite number is a number that has more than 2 factors. Factors are numbers that can divide the given number without leaving a remainder. Composite numbers are not prime numbers, which have exactly 2 factors - 1 and the number itself. For example, 6 is a composite number because it has factors 1, 2, 3, and 6. Choice A is incorrect because it describes a prime number, not a composite number. Choice B is incorrect as being a fraction doesn't determine if a number is composite. Choice D is incorrect because a number with exactly two factors is a prime number, not a composite number.

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: A

Rationale: The correct answer is A because an integer is defined as a whole number that can be positive, negative, or zero. Integers do not include fractions or decimals (eliminating choices B and C) or percentages (eliminating choice D). Integers are the set of numbers {..., -3, -2, -1, 0, 1, 2, 3, ...} and do not include numbers with decimal points or fractions. Therefore, choice A is the only option that accurately describes what defines an integer.

Correct Answer: C

Rationale: To calculate the 16% gratuity on a $58.60 bill, you multiply the bill amount by 0.16 (16%). $58.60 x 0.16 = $9.38. Therefore, the estimated gratuity is $9.38 (Choice C). Incorrect Answers: A: $8.48 - Incorrect, this is not the correct calculation for a 16% gratuity on $58.60. B: $6.40 - Incorrect, this is the calculation for a 11% gratuity on $58.60. D: $7.00 - Incorrect, this is the calculation for a 12% gratuity on $58.60.
