\n" ); document.write( "A typical shared work equation
\n" ); document.write( " $\"8%2F12\"$ + $\"8%2Fc\"$ = 1
\n" ); document.write( "Multiply by 12c, results
\n" ); document.write( "8c + 8(12) = 12c
\n" ); document.write( "96 = 12c - 8c
\n" ); document.write( "4c = 96
\n" ); document.write( "c = $\"96%2F4\"$
