a和b输出反了。。
```cout<<b<<" "<<a<<"\n";```
```cpp
#include <bits/stdc++.h>
using namespace std;
int gcd(int x, int y)
{
while (y ^= x ^= y ^= x %= y)
;
return x;
}
int main()
{
int a, b, c, d;
scanf("%d/%d %d/%d", &a, &b, &c, &d);
a *= c;
b *= d;
int m = gcd(a, b);
a /= m;
b /= m;
cout << b << " " << a << "\n";
return 0;
}
```
