The combining form milli- denotes which fraction?

Explanation:
Understanding metric prefixes and fractions of a unit. Milli- means one thousandth of a unit (10^-3). That’s why a millimeter is 0.001 of a meter and a milliliter is 0.001 of a liter. The root is from Latin mille, meaning thousand. In contrast, centi- is one hundredth (0.01) and deci- is one tenth (0.1), while micro- denotes one millionth (0.000001).
