Answer:

#1/8#

Explanation:

The third decimal place is thousandths so as a starting point write this as:

#125/1000 -=(125-:125)/(1000-:125)= 1/8#

Comment about 1 of many approaches to do with mental arithmetic.

Not that #4xx25=100# so think of 125 as #100+100/4#

#(100+100/4)xx8 = (800+800/4) = 800+200=1000#
