Answer:

Last week, a coral reef grew 19.5 mm taller. How much did it grow in meters?

Step-by-step explanation:

So it's hard to explain but simply Milli witch is the symbol "m" is a unit prefix in the metric system denoting a factor of one thousandth (10 −3).  So 19.6mm is 19.6*10^-3m.  in other words 19.6 times 10^-3m

hope this helps sorry it's so complicated :/
