Hi guys, can someone help me in this code why is it not working properly ?

Question

text = input()
letter = input()
frequency = ((len(letter))/(len(text)))*100
print(int(frequency))

Answer 1

text.count(letter)/len(text)*100

Answer 2

If you are find a letter frequency in word text then len(letter) is 1 only... Whats your idea there?

edit: for any input, it is 1/len(text) *100
hope you can correct it..
