Also describe more explicitly what your specific problem/question is.

You will have to read up heavily on the basics and you should
also make it a habit to use irb for playing around with the different

E.g.:

numbers=[
20222999
20777444
30222999
...
]

This is not even an array and gives a syntax error.
You need to separate array elements by comma.

Or:

numbers.include? ("amounts[0..7]")

This searches for the exact string "amounts[0..7]",
which certainly can not be found in your data.

You mean:

numbers.include?(amounts[0..7])

which doesn't work either because the numbers array will
probably contain integers and amounts[0..7] is a string.

1.9.3p194 :001 > [12345, 23456].include?("12345")
=> false
1.9.3p194 :002 > [12345, 23456].include?(12345)
=> true

and so on...

One approach (there are many) to solve your problem would be:

- split your amounts string into an array of single lines
- go through the array, split each entry into number and amount,
and build a hash with the numbers as keys and
an array with all the amounts for that number as value
