document.write( "Let x be the number of houses under the question.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The rate of work of each builder is  \"12%2F%2816%2A8%29\"  in the first case, in terms of house per day for every builder.\r\n" );

document.write( "\r\n" );
document.write( "The rate of work in the second case is  \"x%2F%288%2A4%29\", in terms of house per day for every builder.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The rate is assumed to be the same in both cases, which gives you a proportion\r\n" );

document.write( "\r\n" );
document.write( "    \"12%2F%2816%2A8%29\" = \"x%2F%288%2A4%29\".\r\n" );

\r\n" );
document.write( "    Actually, you can get the answer without calculations (mentally).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    In the second case the number of workers is half of the first case, and the time is also half of that.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    So, the answer is \"12%2F%282%2A2%29\" = 3 houses, same, as in the solution above.\r\n" );
