全是WA，哪里错了

#include<iostream>
#include<cstdio>
using namespace std;
int main(){
	int n,t,m,a,b,c;
	double mode1,mode2,mode3;
	scanf("%d%d%d",&n,&t,&m);
	scanf("%d%d%d",&a,&b,&c);
	mode1=n/a;
	mode2=t+n/b;
	mode3=m/a+(m+n)/c;
	if(mode3>=mode2){
	    if(mode1>=mode2){
	    	cout<<"MODE II"<<endl;
			printf("%.2f",mode2);
		}
		else cout<<"MODE I"<<endl;
		     printf("%.2f",mode1);
	}
	else cout<<"MODE III"<<endl;
		 printf("%.2f",mode3);
return 0;
}
