TEAS Math Practice Test Questions
Question 1 of 5
Which of the following is NOT a way to write 40 percent of N?
Correct Answer: B
Rationale: The correct answer is B: N/40. To find 40% of N, you multiply N by 0.4, so 0.4N is the correct representation. Choice B, N/40, is incorrect because dividing N by 40 does not give you 40% of N. Choice C, 2/5 N, is equivalent to 40% of N since 2/5 is the same as 40% when simplified. Choice D, 40N/100, is also correct since 40% can be represented as 40/100, which simplifies to 0.4, making 40N/100 another valid way to write 40% of N.
Question 2 of 5
What number is 6 equal to 30% of?
Correct Answer: A
Rationale: To find the number that is 30% of 6, you can set up the equation 0.3x = 6. Solving for x gives x = 6 / 0.3 = 20. Therefore, 6 is equal to 30% of 20. Choice B, 20, is incorrect as it is the result of the calculation. Choice C, 24, and Choice D, 26, are incorrect as they are not the numbers that 6 is equal to 30% of.
Question 3 of 5
What is the value of 0.0523 expressed as a fraction?
Correct Answer: A
Rationale: To convert a decimal to a fraction, place the decimal value over the place value of the last digit. In this case, 0.0523 can be expressed as 523/10000 since the last digit is in the ten-thousandths place. Choice A is correct. Choices B, C, and D are incorrect because they represent different decimal values and do not match the correct conversion of 0.0523.
Question 4 of 5
A scientist is trying to determine how much poison will kill a rat the fastest. Which of the following statements is an example of an appropriate hypothesis?
Correct Answer: C
Rationale: A valid hypothesis must be a testable statement that predicts a relationship between variables. Option C is the only statement that presents a clear cause-and-effect relationship between the amount of poison given and the time it takes for the rat to die. Option A is descriptive without predicting an outcome, option B is a question rather than a statement, and option D is a general fact about poison and rats, lacking a specific hypothesis for testing.
Question 5 of 5
What is the sum of 3/8 and 5/8?
Correct Answer: A
Rationale: In this question, we are asked to find the sum of 3/8 and 5/8. To add fractions, we need a common denominator, which in this case is already 8. Adding 3/8 and 5/8 gives us 8/8, which simplifies to 1 whole unit. Therefore, the correct answer is A) 1. Option B) 1 1/4 is incorrect because the sum of 3/8 and 5/8 is 1, not 1 1/4. Option C) 01-Feb is not a valid fraction representation and does not make mathematical sense in this context. Option D) 03-Apr is also not a valid fraction representation and doesn't align with the correct calculation. Educationally, this question tests students' understanding of adding fractions with common denominators. It reinforces the concept that when the denominators are the same, we simply add or subtract the numerators and keep the denominator the same. Understanding this concept is crucial for more advanced math topics and real-life applications involving fractions.
