Correct Answer: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 30 1/2 = 61/2, and 13 3/4 = 55/4. Then subtract: 61/2 - 55/4 = 122/4 - 55/4 = 67/4 = 16 3/4 (A). Choices B, C, and D are incorrect because they do not represent the correct result of the subtraction calculation.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.

Correct Answer: A

Rationale: To add 5 2/9 and 1 2/9, first add the whole numbers: 5 + 1 = 6. Then add the fractions: 2/9 + 2/9 = 4/9. Combine the whole number and the fraction to get 6 4/9, which is the correct answer (A). Other choices are incorrect because they either do not consider adding the fractions (D), or incorrectly add only the whole numbers (C), or miscalculate the fractions (B).

Correct Answer: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.
