Hello folks!

I'm new here, and this is my question:

If$\displaystyle x = 10^{-3} $so:

$\displaystyle \frac{(0,1).(0,001).10^{-1} }{10.(0,0001)}$is?

I turned all the decimal numbers on '10', and I get $\displaystyle \frac{x}{100}$, but i believe it's not the right result

can you help me, please!?
