Which prefix represents 0.1?

Explanation:
Metric prefixes indicate how a unit is scaled by powers of ten. 0.1 means one tenth, which is 10^-1. The prefix that denotes one tenth is deci, so any unit with this prefix is one tenth of the base unit (for example, a decimeter is 0.1 meter). The other prefixes in this set represent different factors: deka means ten times the unit (10^1), centi means one hundredth (0.01, 10^-2), and milli means one thousandth (0.001, 10^-3). Since the value is 0.1, deci is the appropriate prefix.
