Question

20 da is equal to

A. 20,000 mm.
  B. 2 m.
  C. 20,000 cm.
  D. 2,000 cm.

Answer 1

20,000 mm is the answer

Answer 2

Maybe did you mean dm(decimetre)? If you did, then the answer is:

B. 2m

If you didn't...Well the most close aproximation to that is Da(Dalton) which is a unit of mass, so the options would have not any sense

Step-by-step explanation:

Keep this in mind:

`1dm=0.1m`

and just do the convertions you may need:

`20dm*(0.1m)/(1dm) =2m`
