TEAS Math Practice Test

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.

Correct Answer: B

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.

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: To solve for y, first isolate y by adding 7 to both sides of the equation: 5y - 7 + 7 = 13 + 7. This simplifies to 5y = 20. Then, divide by 5 on both sides to find y = 4. Thus, the correct answer is A: 4. Choices B, C, and D are incorrect as they do not satisfy the equation 5y - 7 = 13.
