TEAS Test Math Questions

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 128 fluid ounces = 1 gallon. Therefore, for 1,000 fluid ounces, we divide 1,000 by 128 to get approximately 7.8125 gallons (A). The correct answer is A because it correctly represents the conversion of fluid ounces to gallons. Choices B, C, and D are incorrect because they do not accurately reflect the conversion factor. B is twice the correct answer, C is four times, and D is eight times the correct conversion.

Correct Answer: C

Rationale: To make a 5:1 solution of water to HCl, we need 5 parts water and 1 part HCl. So, in 2.5 liters, 5/6 parts are water and 1/6 part is HCl. Therefore, 2.5 liters * 1/6 = 0.4167 liters of HCl. As 1 liter of HCl weighs approximately 5 grams, 0.4167 liters would be around 5 * 0.4167 = 2.08 grams. The closest option to this calculated weight is 5 grams (Choice C), making it the correct answer. Choices A, B, and D are incorrect as they do not correspond to the calculated amount of HCl needed for the solution.

Correct Answer: B

Rationale: To find the sum of 4 + 5 + 12 + 9, we add each number sequentially: 4 + 5 = 9 9 + 12 = 21 21 + 9 = 30 Therefore, the correct answer is B: 30. Option A (20), C (40), and D (50) are incorrect as they do not accurately reflect the sum of the given numbers.

Correct Answer: D

Rationale: To find the rate of change in height per month, we multiply the daily growth rate by the number of days in a month. 4.2 inches/day * 30 days = 126 inches/month. Therefore, the correct answer is D. Choice A is incorrect as it is the daily growth rate, not the monthly rate. Choice B is incorrect as it is the same as the daily growth rate, not the monthly rate. Choice C is incorrect as it is not the result of the correct calculation.

Correct Answer: A

Rationale: Correct Answer: A (2) Rationale: 1. When dividing 8 by 4, it means splitting 8 into 4 equal parts. 2. Each part would be 2, as 8 divided by 4 equals 2. 3. Therefore, the result of dividing 8 by 4 is 2. Summary: - Option B (4): Incorrect, as 8 divided by 4 is not 4. - Option C (6): Incorrect, as dividing 8 by 4 does not result in 6. - Option D (8): Incorrect, as the division of 8 by 4 does not yield 8.
