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 input: [1, 2, 3]
Example output: [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.
Q: [-61.308, 43.506, -16.681, 201.542, 141.803, 63.925, -36.177, 154.451, 67.273]
A:
[-0.11   0.078 -0.03   0.361  0.254  0.114 -0.065  0.277  0.12 ]
