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: [64.45, 132.034, 18.267, 145.128, 102.403, -88.328, 80.873, -14.766, -15.901, 242.823]
A:
[ 0.097  0.198  0.027  0.218  0.154 -0.132  0.121 -0.022 -0.024  0.364]
