John is obviously not much of a typist and should just hire Laura to do it.

\n" ); document.write( "\n" ); document.write( "2/18+2/L=1
\n" ); document.write( "2L+36=18L
\n" ); document.write( "36=16L
\n" ); document.write( "9=4L
\n" ); document.write( "9/4=L
\n" ); document.write( "2 1/4=L
\n" ); document.write( "2.25=L
\n" ); document.write( "1/9+2/2.25=1
\n" ); document.write( "1/9+8/9=1
\n" ); document.write( "Laura does 8/9 of the work and John does 1/9 and most of his is probably errors.
