TEAS Math Practice Test Questions
Question 1 of 5
Which number is larger, 0.5 or 1/3?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Convert 1/3 to a decimal: 1 divided by 3 equals 0.3333... 2. Compare 0.5 to 0.3333...; it is evident that 0.5 is larger. 3. Therefore, 0.5 is larger than 1/3. Summary: Choice A is correct as 0.5 is greater than 1/3. Choice B is incorrect as 1/3 is smaller. Choice C is incorrect as they are not equal. Choice D is incorrect as a comparison can be made.
Question 2 of 5
Which of the following is NOT a way to write 40 percent of N?
Correct Answer: B
Rationale: Correct Answer: B Rationale: To find 40% of N, you can multiply N by 0.4 (equivalent to 40/100). Therefore, the correct way is 0.4N. Option B (N/40) is incorrect because dividing N by 40 does not give 40% of N. Option A (0.4N) is correct. Option C (2/5 N) is equivalent to 40%. Option D (40N/100) simplifies to 0.4N, which is correct.
Question 3 of 5
What is the median of the set of numbers {2, 3, 9, 12, 15}?
Correct Answer: B
Rationale: The median is the middle number when the numbers are arranged in ascending order. Step 1: Arrange the numbers in order: {2, 3, 9, 12, 15}. Step 2: The middle number in this set is 9, making it the median. Therefore, the correct answer is B: 9. Choice A (3) is incorrect as it is the smallest number in the set. Choices C (12) and D (15) are incorrect as they are greater than the median value of 9.
Question 4 of 5
What number is 6 equal to 30% of?
Correct Answer: A
Rationale: To find what number is 6 equal to 30% of, we set up the equation: 0.30x = 6. Solving for x, we get x = 6 / 0.30 = 20. Therefore, 6 is equal to 30% of 20. Choice A (18) is incorrect because 30% of 18 is 5.4, not 6. Choices B, C, and D are also incorrect as their respective calculations do not result in 6.
Question 5 of 5
What is the simplified form of the expression (x^2 + 2x)/(x)?
Correct Answer: A
Rationale: To simplify (x^2 + 2x)/(x), we first factor out x from the numerator to get x(x + 2). This simplifies to x + 2 since x/x = 1. Therefore, the correct answer is A: x + 2. Choice B is incorrect because it represents the original expression without simplification. Choice C is incorrect as it is the factored form of the original expression. Choice D is incorrect as it does not simplify to the correct form.
