Question 423926
We can write 500/499 as 1/(499/500).
499/500 = (500 - 1)/500 = 1 - 1/500.  1/500 = 0.002 -> 499/500 = 1 - 0.002.  
We need to solve 1/(1-0.002).  
Multiply numerator and denominator by 1 + 0.002 -> (1)(1+0.002)/(1-0.002)(1+0.002) 
The denominator -> 1 since the 0.002*-0.002 term is very small.
So the answer is approximately 1.002
