==section input Find reciprocal of fraction <TABLE><TR><TD>*[input n=1]</TD></TR><TR><TD>*[input d=2]</TD></TR></TABLE>. ==section solution perl $recip = $d/$n; print "Reciprocal of a fraction is that fraction turned \"upside down\": {{{reciprocal( a/b ) = b/a}}}. In our case, reciprocal of {{{$n/$d}}} is {{{$d/$n}}}, or $recip."; if( length( $recip ) > 8 ) { print "($recip is an approximation). \n"; } ==section output recip ==section check n=1 d=2 recip=2
