#1/8=0.125#

First remember that #8=2 times 4#

and #4=2 times 2#

then #8=2 times 2 times 2#

So, #1/8=1/(2 times 2 times 2)=1/2 times 1/2 times 1/2#

And recall that #1/2# of something is #50%# of that same something

Therefore, #1/8# of something is #1/2# of #1/2# of #50%# of that something

#1/2# of #50# is #25#

and #1/2# of #25# is #12.5#

So #1/8# is the same as #12.5%#

and since a percentage is the same as a decimal # times 100#

We have #1/8=0.125#
