\n" ); document.write( "Draw two pies.
\n" ); document.write( "Split the 1st pie into two parts.
\n" ); document.write( "Split the 2nd pie into three parts.
\n" ); document.write( "---------------------------
\n" ); document.write( "How would you add 1 part of the two to 1 part of the three?
\n" ); document.write( "----------------------------
\n" ); document.write( "Hmmmmmm???
\n" ); document.write( "----------------------------
\n" ); document.write( "Color 1 of the 2 parts; Color 1 part of the three
\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "Split each part of the 1st pie into three parts; you now have 6 parts.
\n" ); document.write( "Split each part of the 2nd pie into two parts; you now have 6 parts
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( "Now you can add the 3 colored parts of the 1st pie to 2 colored parts
\n" ); document.write( "of the 2nd pie to be 5 parts out of 6.
\n" ); document.write( "------------------------------------------
\n" ); document.write( "(1/2) + (1/3) = (3/6) + (2/6) = 5/6
