Correct Answer: C

Rationale: To determine the correct order from least to greatest, convert all fractions to decimals: - (1/7) = 0.142857 - 0.125 - (6/9) = 0.666666 - 0.60 The correct order is 0.125, (1/7), 0.60, (6/9) because 0.125 is the smallest, followed by (1/7), then 0.60, and finally (6/9) which is equivalent to 0.666666. Other choices are incorrect because they do not follow the increasing order of magnitude. Choice A has the fractions in a different order, choice B has 0.60 in the wrong position, and choice D has the fractions in the wrong order. Therefore, choice C is the correct answer.

Correct Answer: D

Rationale: To solve the equation 8x - 6 = 3x + 24, first, simplify both sides. Subtract 3x from both sides to get 5x - 6 = 24. Then, add 6 to both sides to get 5x = 30. Finally, divide by 5 to find x = 6. This is the correct solution as it satisfies the original equation. Choice A, B, and C are incorrect as they do not result in a true statement when substituted back into the equation.

Correct Answer: C

Rationale: To solve the equation 5(4x - 5) = (3/2)(2x - 6), first distribute on both sides to get 20x - 25 = 3x - 9. Then, move x terms to one side and constants to the other side to get 17x = 16. Finally, divide by 17 to find x = 16/17, which is the correct answer (C). The other choices are incorrect because they do not yield the correct value of x when substituted back into the original equation.

Correct Answer: C

Rationale: To round 2.7834 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is 5 or greater, we round up the tenths place digit by 1. Therefore, 2.7834 rounded to the nearest tenth is 2.8 (Choice C). Choice A (2.7) is incorrect because rounding down would be incorrect based on the given number. Choice B (2.78) is incorrect because rounding to the nearest tenth requires looking at the hundredths place. Choice D (2.88) is incorrect as it doesn't follow the rounding rules for the nearest tenth.

Correct Answer: D

Rationale: To calculate the percentage of questions answered correctly, divide the number of correct answers by the total questions and multiply by 100. In this case: (42/48) x 100 = 87.5%. Therefore, choice D (87.50%) is correct. Choice A (1.14%) is too low. Choice B (82.50%) is close but incorrect. Choice C (85.00%) is also close but not the accurate percentage.
