If 1,000 microns = 1 decimeter, and 1,000,000,000 angstroms = 1 decimeter, how many angstroms equal 1 micron?  Select the correct option
A) 1,000  B) 100  C) 1,000,000  D) 10  E) 10,000
Given that 1,000 microns = 1 decimeter =1,000,000,000 angstroms   So, 1 micron = 1,000,000,000/1,000   =1,000,000   Answer : 1,000,000
