What is the problem with my code?

Question

I've wrote this program, but I got every time when I run it 0.0 but I don't know how.

Here is the program:
import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int houses = input.nextInt();
double chances = 0.0;
//your code goes here
double no1 = 2 / houses;
double no2 = no1 *100;

chances = no2;
System.out.println(Math.ceil(chances));
}
}

Answer 1

Kovács Levente do Math.round after Math.ceil and check condition for houses which should be greater than or equals to 3.
