Correct Answer: C

Rationale: To solve 32 divided by 8/9, we convert the division to multiplication by taking the reciprocal of 8/9, which is 9/8. So, 32 ÷ 8/9 becomes 32 x 9/8. Multiply numerators (32 x 9 = 288) and denominators (8) to get 288/8 = 36. Therefore, the correct answer is C: 36. Explanation for other choices: A: 4 & 1/9 - Incorrect because the result is a whole number, not a mixed number. B: 4 - Incorrect as it does not account for the fraction involved in the division. D: 28 & 4/9 - Incorrect as it is not the result of the division calculation.

Correct Answer: D

Rationale: To convert 45 kg to pounds, we use the conversion factor 1 kg = 2.20462 pounds. So, 45 kg * 2.20462 pounds/kg = 99.2079 pounds, which rounds to 110 pounds. Therefore, the correct answer is D. Choice A (10 pounds) is incorrect as it is much lower than the actual conversion. Choice B (100 pounds) is close but slightly lower than the accurate value. Choice C (1,000 pounds) is significantly higher and not a reasonable conversion for 45 kg.

Correct Answer: B

Rationale: To convert inches to feet, divide the number of inches by 12 since there are 12 inches in a foot. 72 inches divided by 12 equals 6 feet. Therefore, the correct answer is B: 6 feet. Choice A (12 feet) is incorrect as it is the conversion of 144 inches, not 72 inches. Choice C (4 feet) and Choice D (17 feet) are also incorrect as they do not accurately represent the conversion of 72 inches to feet.

Correct Answer: D

Rationale: To find the total number of patients seen in 8 hours, first calculate the number of patients seen in 1 hour (25/4 = 6.25). Then, multiply by 8 to get the total (6.25 * 8 = 50). Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not follow the correct calculation process. A, B, and C do not consider the rate of patients seen per hour or the total hours the clinic is open.
