# 程序批注
```cpp
#include<bits/stdc++.h>
using namespace std;
int zhanzhuan(int za,int zb){//尾递归辗转相除
if(za % zb == 0) return zb;
return zhanzhuan(zb,za % zb);
}
int main(){
int mf1 = 0,mm1 = 0,mf2 = 0,mm2 = 0;
char a;//去除‘/’
cin>>mf1>>a>>mm1;
cin>>mf2>>a>>mm2;
int i = zhanzhuan(mf1 * mf2,mm1 * mm2);
cout<<mm1 * mm2 / i<<" "<<mf1 * mf2 / i;
return 0;
}
