Are you allowed to change the sign of ln(something) when moving it to the denominator?

Like for example if I had -ln(something), could i write it as 1/ln(something), and would it be the same thing?

    However , like in another question 

    ln (1/ n) =  -ln(n) 

    examples 

    ln (1/100) =   -4.605170186

    -ln(100) = -4.605170186

    @Michael,that's really something.

    Try it with a number

    let something = 100

    -ln 100 = -4.605170185988091

    1 / ln 100 = 0.217147240951626

    Therefor 

    -ln(something) is NOT 1/ln(something),

    --------------------

    @Charlatan, well it's not 1/something

    Cheers!

    If you refer to one-in-ten versus 1/10, they are mathematically the same, but the grammar of the full sentence or phrase may require other changes.

    One-in-ten people never marry. 1/10 of people never marry.

    I added the word "of".

    The chances of being struck by a bus are one-in-a-million. The chances of being struck by a bus are 1/1,000,000. 

    You do not leave the "in".

    Provide a full phrase or sentence and maybe there is an exception. There are more exceptions than rules in English.
