Sanjay let me finish his box of mints.  He had eaten $$\frac{5}{8}$$ of them.  If $$36$$ mints were left for me, how many mints were there in the box at the start? 
Overseas Competition->Knowledge Point->Word Problem Modules->Solving Problems Involving Fractions and Percentages->Finding the Base
$36\div(1-\dfrac{5}{8})=96$
