TEAS Practice Test Math

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: C

Rationale: To find out how much ammonia is needed, we first calculate the total amount of ammonia needed for 230 gallons of solution. Since 1 gallon requires 6 oz of ammonia, for 230 gallons, we multiply: 230 (gallons) x 6 (oz) = 1380 oz of ammonia. Therefore, the correct answer is C: 1380 oz. Other choices are incorrect because: A: 1380 gallons - This does not make sense as we are calculating the amount of ammonia, not the total volume of cleaning solution. B: 6900 gallons - This is not a logical calculation based on the given information. D: 1400 oz - This is close to the correct answer but miscalculates the total amount of ammonia required.

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 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.

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.
