A reading of 0.625 inch on a micrometer with a 2 to 3 inch range would be equal to _______________.

AI Explanation
The correct answer is A) 2 5/8 inches. A micrometer with a 2 to 3 inch range has a thimble that completes one revolution for every 0.025 inch of movement. Since the reading on the micrometer is 0.625 inch, this corresponds to 2 5/8 inches, which is the correct answer. The other options are incorrect because: B) 2 7/16 inches is too small C) 3 1/8 inches is too large D) 3 9/16 inches is also too large
