Hammer & Screwdriver OK, here is my start at it...
Command instructions
I break up pairs of numbers, and put a ~ marker
get rid of new-line (carriage returns)
replace the ~ after each pair with a new-line; putting pairs on own rows
then do the awk command
Code:
> cat file30 | sed "s/[0-9]*.[0-9]*/&~/g" | tr "\n" " " | tr "~" "\n" | awk '$1*$2>0,z=$1+$2;x=$1/z;y=$2/z {print x,y}'

First couple enty outputs
it is repeating my inputs twice, & not sure why yet (still thinking about that)
then appears to be doing your % as requested
Code:
55 65
55 65
0.458333 0.541667
 48 45
 48 45
0.516129 0.483871

Perhaps this can get you started?
The awk needs to be 'finished'.

Also, the awk might be able to be augmented to use ~ as the RS (record separator). I just had issues trying to get that to work quickly.

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

ENVIRONMENT

     The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7).

EXIT STATUS

     The column utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; 
	   printf "HH:MM/YEAR NAME
" ; 
	   ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.

BUGS

     Input lines are limited to LINE_MAX (2048) bytes in length.
