TEAS Practice Test Math

Correct Answer: A

Rationale: The correct answer is A because a quotient is the result of dividing two numbers. When you divide one number by another, the answer you get is called the quotient. For example, when you divide 10 by 2, the quotient is 5. Choice B is incorrect because the result of multiplying two numbers is called a product, not a quotient. Choice C is incorrect because the number left after subtraction is called a difference, not a quotient. Choice D is incorrect because the number remaining after a division is typically referred to as the remainder, not the quotient.

Correct Answer: A

Rationale: To calculate the number of months, we first subtract the down payment from the total cost to get the remaining balance: $1570 - $400 = $1170. Then, we divide the remaining balance by the monthly payment to determine the number of months: $1170 / $100 = 11.7 months. Since we cannot have partial months in this case, we round up to the nearest whole number, giving us 12 months. Therefore, the correct answer is A (12 months). Choice B (16 months) is too high, Choices C (15 months) and D (11 months) are too low based on the calculations.

Correct Answer: A

Rationale: The correct answer is A because an exponent is a number that indicates how many times a base number is multiplied by itself. For example, in 2^3, 3 is the exponent telling us to multiply 2 by itself 3 times. Choice B is incorrect because an exponent is not the number being multiplied, but the number indicating how many times to multiply. Choice C is incorrect as an exponent does not involve division. Choice D is incorrect as it refers specifically to squaring a number, whereas exponents can apply to any power beyond just squaring.

Correct Answer: A

Rationale: To find the least common denominator (LCD), we need to find the least common multiple (LCM) of the denominators. The denominators are 2, 3, and 5. The LCM of 2, 3, and 5 is 30, which is the smallest number that all three denominators divide into evenly. Therefore, the correct answer is A: 30. Choice B: 25 is not the correct answer because it is not divisible by 2, 3, and 5. Choice C: 7 is not the correct answer because it is not divisible by 2, 3, and 5. Choice D: 19 is not the correct answer because it is not divisible by 2, 3, and 5.

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.
