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: [56.947, 135.313, 42.323, 91.384, 238.648, -28.618, -17.102, 223.252, 67.13]
A:
[ 0.07   0.167  0.052  0.113  0.295 -0.035 -0.021  0.276  0.083]
