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: [130.633, 0.276, 211.746, 81.81, -5.286, 130.004, 148.146]
Student:
[ 0.187  0.     0.304  0.117 -0.008  0.186  0.212]
