In this task, you will be given a list of numbers. The goal is to divide all the numbers in the list by a constant such that the sum of the resulting list is 1. The output should be rounded to 3 decimals.
Example: [1, 2, 3]
Example solution: [0.167, 0.333, 0.500]
Example explanation: The output list sums to 1.0 and has the same weight as the input 0.333 is twice as large as 0.167, .5 is 3 times as large as 0.167, and 0.5 is 1.5 times as large as 0.333. This is a good example.

Problem: [-17.501, 69.581, 247.221, -66.025, 178.815, 248.176, 234.203, 180.882, -38.067]

Solution: [-0.017  0.067  0.238 -0.064  0.172  0.239  0.226  0.174 -0.037]
