Hi

I get this :

[0.0000000027 / 81,000]  /  [  100,000 / 0.000001 ]  =

[ (2.7 x 10^-9) / ( 8.1 x 10^4)] /  [ (1 x 10^5) / 1 x 10^-6) ]  =

[ (2.7 x 10-9) / ( 8.1 x 10^4)] x  [  (1x 10^-6)/ (1 x 10^5)  ]  =

[ 2.7 x 10^-15] /  [ 8.1 x 10^9 ]  =

(2.7 / 8.1)  /  ( 10^-15 / 10^9)  =

_

(1/3) x 10^-24   ≈   0.3    x  10^-24
