C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
  string s1,s2,s3;
  cin>>s1>>s2>>s3;
  s1 = s1.substr(0,s1.length() - 1);
  s2 = s2.substr(0,s2.length() - 1);
  s3 = s3.substr(0,s3.length() - 1);
  cout<<fixed<<setprecision(1)<<80 * atoi(s1.c_str()) / 100.0 <<endl;
  cout<<fixed<<setprecision(1)<<80 * atoi(s2.c_str()) / 100.0 <<endl;
  cout<<fixed<<setprecision(1)<<80 * atoi(s3.c_str()) / 100.0 <<endl;
  cout<<fixed<<setprecision(1)<<80 * (100 - atoi(s1.c_str()) -atoi(s2.c_str()) -atoi(s3.c_str())  )/ 100.0 <<endl;
} 

Java :

import java.util.Scanner;
public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String s = sc.nextLine();
		String[] strs = s.split(" ");
		int left = 100;
		for(int i=0;i<strs.length;i++) {
			if(!strs[i].equals("")) {
				String num = strs[i].split("%")[0];
				int number = Integer.valueOf(num);
				left = left -number;
				System.out.printf("%.1f ",number/100.0 * 80);
			}
		}
		System.out.printf("%.1f ",left/100.0 * 80);
		sc.close();
	}

}

Python :

a,s=[input().split(),0]
for i in a:
    print(round(int(i[:-1])/100*80,1),end=' ')
    s+=int(i[:-1])
print(round((100-s)/100*80,1))
