as,bs,at,bt转成double试试？

把上述四个变量改成double数据类型，亲测已AC

改后代码
```cpp
using namespace std;
int main(){
int n,k,i;
double a,b,as,bs,at,bt;
cin>>n>>k;
for (i=1;i<=n;i++){
if (i%k==0){
at++;
as+=i;
}
else{
bt++;
bs+=i;
}
}
a=as*1.0/at;
b=bs*1.0/bt;
printf("%.1lf %.1lf",a,b);
}

```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
int n,k,a=0,b=0,sum=0,ans=0;
scanf("%d%d",&n,&k);
for(int i=1;i<=n;i++) {
if(i%k==0)
a++;
if(i%k!=0)
b++;
if(i%k==0)
sum=sum+i;
if(i%k!=0)
ans=ans+i;
}
printf("%.1lf",sum/a);
cout <<" ";
printf("%.1lf\n",ans/b);
return 0;
}
```
