What is the least number of people that could be represented by each percentage. Remember, there is no such thing as a "part of a person" in this exercise. The person is alive and whole.
#1. 27.85%
#2. 26.58%
#3. 17.72%
#4. 12.03%
#5. 7.59%
#6. 8.23%

The percentages add up to 100%. The population number is not known by me. I do not have the answer. I am looking to have somebody who understands math to explain how this problem is to be solved and to provide the solution.

I am trying to reply to the posts I made previously. I searched the entire page for an edit or reply. I just couldn't find one. I also couldn't rate the answers. It says I should be level 2 for that. I won't be able to reply to this post too. How do I reply to posts in my own thread? Yes, there is no edit or reply button in my post and I am in level 2, incase this information can be of some use to you all!
