Let $\"+x+\"$ = original amount of dirt
\n" ); document.write( " $\"+%283%2F4%29%2Ax+\"$ is poured out, and
\n" ); document.write( " $\"+%281%2F4%29%2Ax+\"$ remains in the bucket
\n" ); document.write( "------------
\n" ); document.write( " $\"+%282%2F3%29%2A%283%2F4%29%2Ax+=+%281%2F2%29%2Ax+\"$ is poured back in
\n" ); document.write( " $\"+%281%2F4+%2B+1%2F2%29%2Ax+=+%283%2F4%29%2Ax+\"$ is now in the bucket
\n" ); document.write( "20% is spilled out, so 80% remains
\n" ); document.write( "80% = $\"+4%2F5+\"$
\n" ); document.write( " $\"+%284%2F5%29%2A%283%2F4%29%2Ax+=+%283%2F5%29%2Ax+\"$
\n" ); document.write( " $\"+3%2F5\"$ = 60%
\n" ); document.write( "60% of the original dirt remains in the bucket
\n" ); document.write( " \n" ); document.write( "

\n" );
