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: [48.454, 17.025, 20.947, -30.65, 220.836, 98.587, 38.934, -60.132, 85.511]

Solution: [ 0.11   0.039  0.048 -0.07   0.502  0.224  0.089 -0.137  0.195]
