TEAS Practice Test Math

Correct Answer: A

Rationale: To simplify 3.45 * 0.53, multiply the numbers together: 3.45 * 0.53 = 1.8285 (Answer A). This is correct because when multiplying decimals, you multiply as if they were whole numbers and then place the decimal point in the answer based on the total number of decimal places in the factors. Summary of other choices: B: 18.285 - Incorrect as it is the result of adding the two numbers. C: 0.18285 - Incorrect as it is the result of placing the decimal point incorrectly. D: 182.85 - Incorrect as it is the result of ignoring the decimal places in the factors.

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: C

Rationale: To find the amount the friend paid for their car, we need to set up an equation. Let x be the friend's car price. The consumer paid $48,000, which is $2,000 less than twice the friend's car price, so 2x - $2,000 = $48,000. Solving for x, 2x = $48,000 + $2,000 = $50,000, therefore x = $25,000. Choice C is correct. Choices A, B, and D do not satisfy the given condition in the question. A is less than $25,000, B is greater than $25,000 but not $2,000 less than twice, and D is greater than $25,000.

Correct Answer: D

Rationale: The correct answer is D: 25 g. A pencil is a lightweight object typically weighing in grams, not kilograms, centimeters, or milligrams. The weight of 25 g aligns with the standard weight of a pencil. Kilograms (A) are too heavy, centimeters (B) are units of length, and milligrams (C) are too light for a pencil's weight. So, the most likely weight of a pencil is 25 grams.

Correct Answer: D

Rationale: To find the correct amount of vanilla in mL, first, multiply 5.5 (teaspoons) by 4.93 (mL per teaspoon) to get 27.115 mL. Then round to the nearest whole number, giving 27 mL. Therefore, choice D is correct. Choices A, B, and C are incorrect as they do not result from the correct conversion calculation.
