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: [-31.476, 12.568, 222.668, -30.557, -30.581, 138.389, -29.952, 179.05, 142.733, 141.505]
A:
[-0.044  0.018  0.312 -0.043 -0.043  0.194 -0.042  0.251  0.2    0.198]
