hurry up guys i cant take forever on this ;/

apoorvk · Answer

yeah 100 milimeters = 1 decimeter correct!!

apoorvk · Answer

and now, 4 milimeters is scaled 5 decimeters, which is 500 milimeters! right?

apoorvk · Answer

so, scale factor = (final size)/(initial size)

anonymous · Answer

1 decimeter = 100 millimeters 
 5 dm           = 5*100
  5dm           = 500 mm
