Final answer:
The most precise measurement from the given list is option E, which is 4 5/16, as it has the smallest parts in the fraction indicating a higher level of precision.
Step-by-step explanation:
To choose the most precise measurement from the list provided, we need to look at the fractions and determine which one can be subdivided into the smallest parts, resulting in the most exact value. The options given are A. 6 2/8, B. 4 1/4. C. 6 4/16, D. 7 8/32, E. 4 5/16. To compare the precision of these measurements, we must first simplify the fractions: A becomes 6 1/4 after simplification. B remains 4 1/4. C becomes 6 1/4 after simplification. D becomes 7 1/4 after simplification. E remains 4 5/16 and is already in its simplest form. Since option E has a denominator of 16, which is more subdivided than the other options, it is the most precise measurement.
