Basically you have to convert the equalities in each box.
I'll help you figure out what the equalities are and hopefully you can figure it out from there.
Milli= .001
Centi= .01
Deci= .1
Unit base=1
Deka= 10
Hecto= 100
Kilo= 1000
In the first box, it asks for you to convert a millimeter into a meter
1mm=.001m
If you have any more trouble, please message me. I'd be happy to help
