Help me with phyton

Question

https://www.sololearn.com/coach/4?ref=app
In this challenge my answer is:
houses = int(input())
print(int(round((2/houses)*100)))

First two test cases are correct 💯, others are incorrect 😔 but they are locked 🔐. So I can't figure out the problem 😕.
Please help me.

Answer 1

As the output format required, "a percentage value ROUNDED UP..."

Answer 2

import math library and use ceil instead of round.
