you know to count intervels with the SCALE notes(eg every interval) do I first need to know the scales?

and ome more thing -

F-D = 6th
B-flat-C# = 2nd
G#-B-flat = 3rd

How do I know what scale these are from..does it matter? hmm:/...

I really appreciate all the answers - I will also choose a best one
from now.
