Answer 2

   

$Let\ \ x = 0.\overline{001} = 0.001001001... \\ \\ \\ \Rightarrow\ x=0.\overline{001} \\ \\ \Rightarrow\ 1000x=0.\overline{001} \times 1000 \\ \\ \Rightarrow\ 1000x = 1.\overline{001} \\ \\ \\ \Rightarrow\ 1000x-x=1.\overline{001}-0.\overline{001} \\ \\ \Rightarrow\ 999x=1 \\ \\ \Rightarrow\ x=\bold{\frac{1}{999}} \\ \\ \Rightarrow\ \frac{p}{q}=\bold{\frac{1}{999}}$
