In one hour Jack mows 1/5 of the lawn
\n" ); document.write( "In one hour Mary mows 1/3 of the lawn
\n" ); document.write( "so we would think that together they can mow in less than 3 hours
\n" ); document.write( "x/5+x/3=1
\n" ); document.write( "15/8 hrs.=1.875 hrs. =1:52.5 hrs. almost two hours\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "15/(8*5)+15/(8*3)=1
\n" ); document.write( "Jack mows 3/8 and Mary mows 5/8
\n" ); document.write( "3/8+5/8=1
\n" ); document.write( "
\n" ); document.write( "
