document.write( "**1. How many more rows were filled on the first train than on the third train?**\r<BR>\n" );
document.write( "\n" );
document.write( "* First train: 7 1/4 rows = 7.25 rows<BR>\n" );
document.write( "* Third train: 5 1/2 rows = 5.5 rows<BR>\n" );
document.write( "* Difference: 7.25 - 5.5 = 1.75 rows\r<BR>\n" );
document.write( "\n" );
document.write( "**Answer:** 1.75 more rows were filled on the first train than the third train.\r<BR>\n" );
