May be I haven't explained well enogu. Here is my real example.
I have 73 sets, each set containing 4 columns (example red and blue) and unique header.

input
Code:
gName	1_rawcounts	1_KPM	1.ed(all reads)	1_total_length	21_rawcounts	21_KPM	21.ed(all reads)	21_total_length
E3_c1-	0	0	8820373	2069	0	0	11485482	2069
E3_c2-	0	0	8820373	2069	0	0	11485482	2069
E3_c3-	0	0	8820373	2069	0	0	11485482	2069
E3_c4-	0	0	8820373	2069	0	0	11485482	2069

Code:
awk '{print ($2/$5) / ($4 / $5) "\t" ($6/$9) / ($8/$9)}' input

needed output
Code:
gName	1	21
E3_c1-	0	0
E3_c2-	0	0
E3_c3-	0	0
E3_c4-	0	0
