结构和数组的结合哪里出错了？

Question

#include <stdio.h>
struct number{
int fenzi;
int fenmu;
};
int main()
{
struct number numbers[2];
for(int i=0;i<=1;i++)
{
scanf("%d/%d",&numbers[i].fenzi,&numbers[i].fenmu);
if(numbers[0].fenzi1.0/numbers[0].fenmu>numbers[1].fenzi1.0/numbers[1].fenmu)
printf("%d/%d > %d/%d",numbers[0].fenzi,numbers[0].fenmu,numbers[1].fenzi,numbers[1].fenmu);
else if(numbers[0].fenzi1.0/numbers[0].fenmu==numbers[1].fenzi1.0/numbers[1].fenmu)
printf("%d/%d < %d/%d",numbers[0].fenzi,numbers[0].fenmu,numbers[1].fenzi,numbers[1].fenmu);
else
printf("%d/%d = %d/%d",numbers[0].fenzi,numbers[0].fenmu,numbers[1].fenzi,numbers[1].fenmu);
}
return 0;
}
