A drill bit is stamped 0.375 inch. Which fractional bit size is the same measurement?

Correct answer to question 25 (Arithmetic Reasoning): 3/8 inch

Method

Convert the decimal to a fraction over a power of ten: 0.375 is 375/1000, and dividing top and bottom by 125 gives 3/8. Shop measurements are usually marked in eighths and sixteenths, so this is a conversion worth knowing on sight.
