The two equations aren't exactly identical.
The first equation:
100*(1+10%)=100*11/10=100*1.1=110
The second equation:
100/(1-10%)=100*10/9=100*1.1111...=111.111...
There's about a 1% difference between the two equations. The first
equation increases 100 by exactly 10%. The second equation increases
by 11.1%
