import java.util.*;

public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int houses = input.nextInt();

double percent;
percent = 2 / houses * 100;
System.out.print(Math.ceil(percent));
}
}

Answer 1

because you provide 2 as integer, so division is whole division...

try:

percent = 2.0 / houses * 100;
