It's a bit hard to tell what exactly your array looks like, but I'm going to take a guess:

element = ['car;dog;soda',
           'bunny;pc;laptop',
           'hand;sword;shield']

If that's correct, you can get the output you are looking for with something like:

element.each_index {|i| element[i] = element[i].gsub(';', "#{i+1};")}

The each_index iterator gives you each index (unsurprisingly). Then you can use each index to manipulate each value in the array.
