Combined rate = (1 lawn / 2 hrs) + (1 lawn / 4 hrs)
\n" ); document.write( " $\"1%2F2+%2B+1%2F4+=+2%2F4+%2B+1%2F4\"$
\n" ); document.write( " $\"2%2F4+%2B+1%2F4+=+3%2F4\"$
\n" ); document.write( "This says together they can mow 3 lawns in 4 hours
\n" ); document.write( "divide top and bottom by 3
\n" ); document.write( " $\"%283%2F3%29+%2F+%284%2F3%29+=+1+%2F+%284%2F3%29\"$
\n" ); document.write( "So, together, they can mow 1 lawn in 4/3 of an hour or 1 hour 20 minutes \n" ); document.write( "
