Question 656424
In this problem we know that the pie is cut into eighths by observing the denominators. Imagine a pie cut into 8 slices which make up the whole pie. Each slice represents {{{1/8}}}. So 8 of the {{{1/8}}} slices make up the entire pie. We write this as: {{{8/8}}, which reduced will give you 1. The 1, represents the "whole" pie. 

But we do not want to reduce, so let's start with{{{8/8}}}, which represents the whole pie and then subtract Diane's {{{3/8}}} and Vaniece's {{{3/8}}}.

{{{8/8}}} - {{{3/8 }}}- {{{3/8}}} = {{{2/8 }}}

Therefore, {{{2/8}}} of the pie is left over to eat. This can be reduced:
{{{2/8 = 1/4}}}
