5/6 = 83% 
1/6= 16%
83% of the apple pie was left from dinner. 
Victor is gonna eat 16% of the pie tomorrow 
You have to subtract 16% from 83%
In other words 5/6-1/6
The denominators are same so you don't have to do anything to them  
5/6 - 1/6 
5-1=4
4/6 of the pie would be left 
In simplest form it would be 
4/6     <span> ÷2</span>
=2/3
2/3 is in simplest form
