Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[1, 2, 3]
Solution: [0.167, 0.333, 0.500]
Reason: 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.

Now, solve this instance: [62.253, 23.424, 159.316, -91.619, 116.729, 104.726, -87.295, 7.852, 223.702]
Student:
[ 0.12   0.045  0.307 -0.176  0.225  0.202 -0.168  0.015  0.431]
