《```b3=b1*b3;```》

```c
#include<iostream>
#include<cstdio>
#include<algorithm> //就我所知，__gcd()应该在这里面
#include<string>
#include<cstring>
using namespace std;
int a1,a2,b1,b2;
char spc;
int main()
{
scanf("%d",&a1); spc=getchar(); scanf("%d",&b1);
//spc用于读掉除号
scanf("%d",&a2); spc=getchar(); scanf("%d",&b2);
int c1=a1*a2,c2=b2*b1;
printf("%d %d\n",c2 / __gcd(c1,c2),c1 / __gcd(c1,c2));
//约分
return 0;
}
```
这很简单呀
