Question 907619
Your difficulty is part of why arithmetic is useful for computing with numerals written in digits.


You want to cut {{{3/5}}} of a pie into 5 equal pieces.  This could still be done using a drawing.  You want  {{{3/5}}} DIVIDED BY  {{{5}}}.


This is the same as {{{(3/5)/5}}};
which is
{{{(3/5)(1/5)}}}
{{{3/(5*5)}}}
{{{highlight(3/25)}}}.


If you want to try using a drawing or picture, use a rectangle or a square; instead of a circular pie-shaped drawing.  Forming a grid to represent the number will be much easier for this kind of situation.
