TEAS Math Practice Test

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.

Correct Answer: A

Rationale: To find 15% of 200, you multiply 200 by 0.15 (which is the decimal equivalent of 15%). 200 * 0.15 = 30. Therefore, the correct answer is A (30). Option B (20) is incorrect because it represents 10% of 200. Option C (25) is incorrect as it is not the result of calculating 15% of 200. Option D (40) is incorrect as it is the result of multiplying 20% by 200.

Correct Answer: A

Rationale: To convert 3 5/7 to an improper fraction, multiply the whole number (3) by the denominator (7) and add the numerator (5) to get 26. The denominator remains the same, resulting in 26/7. This is the correct answer because it represents the mixed number 3 5/7 in fraction form. Choice B (21/7) simplifies to 3, which is the whole number part of the mixed number. Choice C (22/7) is equivalent to the approximation of π and not the correct conversion of 3 5/7. Choice D (26/5) is incorrect as it does not represent the mixed number 3 5/7 accurately.

Correct Answer: D

Rationale: To find the fraction the fourth person pays, we need to calculate the sum of fractions paid by the first three people. 1/3 + 1/4 + 1/6 = 4/12 + 3/12 + 2/12 = 9/12. Therefore, the fourth person pays 1 - 9/12 = 3/12 or 1/4 of the bill. Choice D (1/12) is incorrect as it does not account for the fractions paid by the other three people. Choices A (1/4), B (1/6), and C (1/3) are incorrect as they represent the fractions paid by other individuals, not the fourth person.

Correct Answer: A

Rationale: To round 847.89632 to the nearest hundredth, we look at the digit in the thousandth place, which is 6. Since 6 is greater than or equal to 5, we round up the digit in the hundredth place (9) by 1, making it 10. Therefore, the number becomes 847.90 (answer A). Choice B (900) is incorrect as it rounds to the nearest whole number. Choice C (847.89) is incorrect as it rounds down. Choice D (847.896) is incorrect as it does not round to the nearest hundredth.
