Question

What is this I'm lost

Answer 1

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
