in the metric system, one millimeter equals how many centimeters?\n1/1000\n1/100\n1/10\n10

Brief Explanations:

The metric - system prefixes: milli - means one - thousandth ($10^{- 3}$) and centi - means one - hundredth ($10^{-2}$). Since 1 millimeter ($10^{-3}$ m) and 1 centimeter ($10^{-2}$ m), to convert millimeters to centimeters, we use the conversion factor. 1 mm=$\frac{1}{10}$ cm because $\frac{10^{-3}}{10^{-2}}=\frac{1}{10}$.

Answer:

C. 1/10
