TEAS Test Math Questions Questions
Question 1 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.
Question 2 of 5
Evaluate the expression -3 x 5.
Correct Answer: A
Rationale: To evaluate -3 x 5, we multiply -3 by 5 which gives us -15. The correct answer is A (-15) because when multiplying a negative and a positive number, the result is negative. Choice B (-2) is incorrect as it is the result of adding -3 and 5. Choice C (2) is incorrect as it is the result of multiplying -3 and -5. Choice D (15) is incorrect as it is the result of multiplying 3 and 5, not -3 and 5.
Question 3 of 5
If a tree grows an average of 4.2 inches in a day, what is the rate of change in its height per month? Assume a month is 30 days.
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.
Question 4 of 5
A sign stating 'Do Not Enter' is in the shape of a square with side lengths of 75 centimeters. What is the area in square centimeters?
Correct Answer: D
Rationale: To find the area of a square, you square the length of one side. In this case, the side length is 75 cm. Therefore, the area is 75 cm x 75 cm = 5,625 square cm. Option D is correct. Option A (150) is too small as it represents the perimeter of the square. Option B (300) is incorrect as it is half the correct area. Option C (5,325) is incorrect as it is much larger than the correct area.
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.
