} @lelaimc 1.

include<bits/stdc++.h>

using namespace std; int main() { int a,b,k,n,sum=0,ans=0; double p1,p2; cin>>n>>k; for(int i=1;i<=n;i++){ if(i%k==0){ a+=i; sum++;} else if(i%k!=0){ b+=i; ans++; } } p1=a1.0/sum; p2=b1.0/ans; cout<<fixed<<setprecision(1)<<p1<<endl; cout<<fixed<<setprecision(1)<<p2<<endl; return 0; }

#include <iostream>
#include <cstdio>
using namespace std;

    int n,k;
    double numa,numb,anda,andb;
    cin>>n>>k;
    for(int a=1;a<=n;a=a+1)
    {
        if(a%k==0)
        {
            numa=numa+1;
            anda=anda+a;
        }
        else

            andb=andb+a;
        }
    }
    printf("%.1lf",anda/numa);
    cout<<" ";
    printf("%.1lf",andb/numb);
    return 0;
