TEAS Math Practice Test

Correct Answer: A

Rationale: To round 245.2678 to the nearest thousandth, we look at the digit in the thousandths place, which is 7. Since 7 is greater than or equal to 5, we round up. The ten-thousandths place, denoted by the digit 8 in this case, is used to decide whether to round up or down when rounding to the nearest thousandth. The correct answer is A (Ten-thousandths). Summary: A: Ten-thousandths - Correct, used to decide rounding up or down in rounding to the nearest thousandth. B: Thousandths - Incorrect, this is the place being rounded to. C: Hundredths - Incorrect, not relevant for rounding to the nearest thousandth. D: Thousand - Incorrect, not relevant for rounding to the nearest thousandth.

Correct Answer: C

Rationale: To find the fraction of blue shirts, we need to subtract the fractions of green and red shirts from 1 (total). Given that 1/4 are green and 1/3 are red, the fraction of blue shirts is 1 - 1/4 - 1/3 = 12/12 - 3/12 - 4/12 = 5/12. Therefore, the correct answer is C: 5/12. Choice A (1/2) is incorrect as it doesn't consider the given fractions of green and red shirts. Choice B (1/3) is incorrect as it only considers the fraction of red shirts. Choice D (1/4) is incorrect as it only considers the fraction of green shirts.

Correct Answer: A

Rationale: The correct answer is A: 75 dollars per gigabyte. The slope of the equation represents the rate of change in cost per unit change in data usage. In this case, for every additional gigabyte of data used (D), the cost of the phone bill (C) increases by $75. This interpretation aligns with the equation C = 50 + 75D, where 75 is the coefficient of D, indicating the cost per gigabyte. Summary of other choices: B: 75 gigabytes per day - This is incorrect as it does not reflect the cost per gigabyte relationship in the equation. C: 50 dollars per day - This is incorrect as it does not account for the cost associated with data usage. D: 50 dollars per gigabyte - This is incorrect because the correct cost per gigabyte is $75, not $50.

Correct Answer: D

Rationale: Correct Answer: D (1 apple) Rationale: 1. Xavier starts with 20 apples. 2. He gives half to Emma, leaving him with 10 apples. 3. He gives 6 apples to Jim, leaving him with 4 apples. 4. He uses 3/4 of his remaining 4 apples for the pie, leaving him with 1 apple. Summary: - Choice A (4 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie. - Choice B (6 apples) is incorrect because Xavier gives 6 apples to Jim. - Choice C (2 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie.

Correct Answer: B

Rationale: To convert 1.25 to a fraction, we note that the decimal has two decimal places. To convert it to a fraction, we write 1.25 as 125/100. Simplifying by dividing both numerator and denominator by 25, we get 5/4. Therefore, the correct answer is B: 5/4. A: 1 1/4 is the mixed number form of 5/4. C: 4/5 is the reciprocal of the correct answer. D: 25/20 is not simplified; it should be reduced to 5/4.
