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: B

Rationale: To find the difference between two negative numbers, we subtract the second negative number from the first. When we subtract a negative number from another negative number, it is equivalent to adding the positive value of the second number to the first number. This results in a positive number as the answer, making choice B (Positive number) the correct answer. Choices A, C, and D are incorrect because the result of subtracting two negative numbers is always a positive number, not another negative number, zero, or not enough information.

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: B

Rationale: To find the median, we first arrange the data set in ascending order: 3, 5, 7, 9, 11. The median is the middle value when the data is ordered, which is 7 in this case. To confirm, count the numbers: there are 5 data points, making 7 the third value from both ends. Therefore, the median of the data set is 7. Choice A (3) is incorrect because it is the smallest value in the data set. Choice C (9) is incorrect because it is the second largest value in the data set. Choice D (5) is incorrect because it is the second smallest value in the data set.

Correct Answer: D

Rationale: To simplify the expression 3x - 5x + 2, we first combine like terms. 3x - 5x = -2x, so the expression becomes -2x + 2. Thus, the correct answer is D: -2x. Choice A is incorrect as it incorrectly combines the x terms without changing their signs. Choice B is incorrect as it only considers the x terms and ignores the constant term. Choice C is incorrect as it incorrectly combines the x terms without changing their signs.
