Answer:
Milli
Explanation:
centi means hundredth(0.01)
deca means tenth(10)

milli means thousandth(0.001)
When you think of centi think of pennies or cents. There are 100 pennies in a dollar. Or a cent is %0.01 of a dollar.
When you think of deca think of a decade - a span of 10 years.
When you think of deci think of a decimal. Because well that's what the decimal is named after. It's used to seperate the ones and tenths place.
English is a bit confusing, so when you think of milli you probably think of million. Instead, think of the Spanish word for thousand which is 'mil'. Milli is the mil little it is the thousand which is little.
