The equation is \"x%281%2F3+%2B+1%2F4%29+=+7\"
\n" ); document.write( "Notice the right-hand side of the equation is not equal to 1, because we're not dealing with only 1 WHOLE quantity, but 7 WHOLE quantities.\r
\n" ); document.write( "\n" ); document.write( "==> \"%287x%29%2F12+=+7\" <==> x = 12 hours.
\n" ); document.write( "
