TEAS Practice Test Math

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: C

Rationale: To find the product of 1.6 and 0.93, we multiply the two numbers as usual: 1.6 * 0.93 = 1.488. The correct decimal placement for the product is C (1.488) because when multiplying decimal numbers, the total number of decimal places in the product should be equal to the sum of decimal places in the numbers being multiplied. In this case, 1.6 has one decimal place and 0.93 has two decimal places, totaling three decimal places. Therefore, the correct answer is 1.488, as it has three decimal places. Explanation for other choices: A: 14.88 - Incorrect as it has an extra decimal place. B: 0.1488 - Incorrect as it has one less decimal place. D: 0.001488 - Incorrect as it has more decimal places than the product of 1.6 * 0.93.

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A because the greatest common factor is the largest factor that divides all the given numbers without a remainder. This factor is common to all numbers and is the greatest among all the common factors. Choice B is incorrect because the smallest factor does not account for all numbers. Choice C is incorrect as the greatest common factor is not a multiple, but a factor. Choice D is incorrect since the smallest multiple does not necessarily divide all the numbers without a remainder.

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.
