How would you read 0.002 inches?

Reading 0.002 inches as "two thousandths of an inch" is accurate because the decimal notation explicitly indicates the fractional part of an inch in terms of thousands. In the decimal system, the position of each digit reflects its value relative to the whole.

In this case, the number 2 is in the thousandths place, which means it represents two out of a total of one thousand parts of an inch. Thus, it corresponds to two thousandths, or 2/1000 of an inch.

Understanding this decimal structure is crucial in measurements, especially in fields such as engineering or machining, where precise dimensions are vital. The other choices do not accurately reflect the value of the number in question; they either misinterpret the decimal placement or suggest a different fractional relation to an inch.
