You can put this solution on YOUR website! 0.125 in fraction form. It has 3 decimals, so:
0.125 = 125/1000 divide both numbers by 25:
5/40 these are both divisible by 5
1/8 we can't reduce it any more.
You can do the same for 75%:
75% = 0.75; two decimals: 75/100 divide by 25:3/4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now we have:

7/8+x = 1
x = 1/1-7/8 = 8/8-7/8 = 1/8 is your answer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:
1/8+6/8+1/8 = 8/8 simplify: 8/8 = 1 slab. Correct.
