#include <iostream>

using namespace std;

struct Rational
{
    int n;
    int d;
};

int main()
{
    char op;
    struct Rational raleft;
    cin>>raleft.n>>op>>raleft.d;

    struct Rational raright;
    cin>>raright.n>>op>>raright.d;

    if(raleft.n*raright.d > raright.n * raleft.d)
        cout<< raleft.n<<"/"<<raleft.d<<" > "<<raright.n<<"/"<<raright.d<<endl;

    if(raleft.n*raright.d == raright.n * raleft.d)
        cout<< raleft.n<<"/"<<raleft.d<<" = "<<raright.n<<"/"<<raright.d<<endl;

    if(raleft.n*raright.d < raright.n * raleft.d)
        cout<< raleft.n<<"/"<<raleft.d<<" < "<<raright.n<<"/"<<raright.d<<endl;

    return 0;
