Whenever I try to write this code for number 3:

```
percentage_ceballos = total_ceballos/len(survey_responses)
```

It prints out 0 and I can’t understand why.

Then when I put 100 * in front of it:

```
percentage_ceballos =100 * total_ceballos/len(survey_responses)
```

It prints out 47, the desired answer.

Similarly, the answer is this:

```
percentage_ceballos = total_ceballos/float(len(survey_responses))
```

Why does that fix the problem as well?
