#include<bits/stdc++.h>
using namespace std;
int n,k,a,b,sa,sb;
int main(){
    cin>>n>>k;
    for(int i=1;i<=n;i++){
        if(i%k==0) a+=i,sa++;
        else b+=i,sb++;
    }
    printf("%.1lf %.1lf",(double)(a/sa),(double)(b/sb));
}

申明变量时直接用double就没问题了

@chenkuochenkuo 样例没过，应该输出 56.0 50.1，但你的代码输出56.0 50.0

@chenkuochenkuo 输出部分改成printf("%.1lf %.1lf",(double)(a*1.0/sa),(double)(b*1.0/sb));
