TEAS Math Practice Test Questions
Question 1 of 5
What is the simplified form of the expression (x^2 + 2x)/(x)?
Correct Answer: A
Rationale:
To simplify the expression (x^2 + 2x)/(x), we factor out x from the numerator to get x(x + 2) and then cancel the x in the denominator. This simplifies to x + 2, making choice A the correct answer.
Choice B (x^2 + 2) is incorrect as it does not account for the division by x.
Choice C (x(x + 2)) is also incorrect as it represents the factored form before cancellation.
Choice D (1 + 2/x) is incorrect as it does not simplify the expression correctly.
Question 2 of 5
How will the number 847.89632 be written if rounded to the nearest hundredth?
Correct Answer: A
Rationale: When rounding to the nearest hundredth, we look at the digit in the thousandth place, which is 8. Since the next digit, in the ten-thousandth place, is 9 (greater than or equal to 5), we round up the hundredth place digit.
Therefore, 847.89632 rounded to the nearest hundredth is 847.90.
Choice B (900) is incorrect as it does not round the number to the nearest hundredth.
Choice C (847.89) is also incorrect as it drops the digit 6 in the ten-thousandth place.
Choice D (847.896) does not round the number to the nearest hundredth as it retains the thousandth place digit 3.
Question 3 of 5
What is the mode of the set of numbers {4, 4, 5, 7, 8}?
Correct Answer: A
Rationale: The mode of a set of numbers is the value that appears most frequently. In the given set {4, 4, 5, 7, 8}, the number 4 appears twice, which is more frequent than any other number.
Therefore, the mode of this set is 4.
Choice B, 5, is incorrect as it only appears once in the set.
Choices C and D, 7 and 8 respectively, also appear only once each, making them less frequent than the number 4.
Question 4 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 5 of 5
Which number is larger, 0.5 or 1/3?
Correct Answer: A
Rationale:
To compare 0.5 and 1/3, we can convert 0.5 to a fraction, which is 1/2. When comparing 1/2 and 1/3, we find that 1/2 is greater than 1/3.
Therefore, 0.5 is larger than 1/3.
Choice B is incorrect as 1/3 is smaller.
Choice C is incorrect as the numbers are not equal.
Choice D is incorrect as a clear comparison can be made.
