Final answer:
The measurement conversion 84cm = 8.4mm is incorrect. The correct conversion would be 84cm = 840mm. All other conversions provided are correct.
Explanation:
The question asks which of the following measurements are not equivalent: A. 25mg = 0.025g B. 24dL= 2.4L C. 183L=0.183kL D. 84cm=8.4mm E. 150ms=0.150s. To answer this question, we need to convert each of these measurements to confirm whether they are correct or not.
A. 25mg = 0.025g: This is correct as 1g = 1000mg. B. 24dL = 2.4L : This is correct as 1L = 10dL. C. 183L = 0.183kL: This is correct, as 1kL = 1000L. D. 84cm = 8.4mm: This is incorrect because 1cm = 10mm. Therefore, 84cm = 840mm. E. 150ms = 0.150s: This is correct because 1s = 1000ms.
