The first mower can mow \"1%2F7\" of the yard in 1 hour.
\n" ); document.write( "The second mower can mow \"1%2F6\" of the yard in 1 hour.
\n" ); document.write( "Together, they can mow \"1%2F7+%2B+1%2F6+=+13%2F42\" of the yard in 1 hour.
\n" ); document.write( "So it would take them \"42%2F13\" hours to mow the entire yard.
\n" ); document.write( "\"42%2F13+=+3.2307\" hours.
\n" ); document.write( "Rounded to the nearest tenth this would be 3.2 hours.
