TEAS Test Math Questions Questions
Question 1 of 5
What is the mean for the data set 16, 18, 17, 15, 19, 14, 12, 11, 10, 16, 18, and 17?
Correct Answer: C
Rationale: To find the mean, sum all values and divide by the total count. For this data set, sum = 16+18+17+15+19+14+12+11+10+16+18+17 = 183. Total count = 12. Mean = 183/12 = 15.25, which makes choice C, 16, the correct answer. Choice A, 14.25, and B, 15.25, are incorrect as they do not match the calculated mean. Choice D, 17, is incorrect as it is higher than the calculated mean value.
Question 2 of 5
Which decimal is the smallest?
Correct Answer: C
Rationale: To determine the smallest decimal, compare the digits from left to right. In choice C (2.002), the first non-zero digit is in the thousandths place, making it smaller than choices A, B, and D. Choice A (2.22) has the first non-zero digit in the tenths place, making it larger than choice C. Choice B (2.02) has a smaller tenths place digit than choice A but a larger hundredths place digit, still making it larger than choice C. Choice D (2.2) has the first non-zero digit in the tenths place, which is larger than choice C. Therefore, the correct answer is C (2.002) as it has the smallest value among the given options.
Question 3 of 5
What is the result of multiplying 3/5 by 5/7?
Correct Answer: A
Rationale: To find the result of multiplying fractions, you simply multiply the numerators together and the denominators together. For 3/5 * 5/7: (3*5) / (5*7) = 15 / 35, which simplifies to 3/7. Thus, the correct answer is A: 3/7. Other choices are incorrect because they do not result from the correct multiplication process. B: 1 is the result of multiplying any fraction by its reciprocal, while C: 2 and D: 4 are not valid outcomes of this specific multiplication.
Question 4 of 5
What is the difference between two equal numbers?
Correct Answer: C
Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.
Question 5 of 5
Which proportion yields a different number for the unknown compared to the others?
Correct Answer: D
Rationale: To determine the correct answer, we need to find the value of x in each proportion. For choice A, x = 4; for choice B, x = 8; for choice C, x = 6; and for choice D, x = 10. So, the correct answer is D because it yields a different value for x compared to the other choices. Choices A, B, and C all have x values that are multiples of 2, whereas choice D has a different x value. Therefore, choice D is the only proportion that yields a different number for the unknown compared to the others.
