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: [-32.052, 228.379, 95.125, 225.531, 72.339, 121.127, -62.977, 6.17, -78.78]
A:
[-0.056  0.397  0.165  0.392  0.126  0.211 -0.11   0.011 -0.137]
