To me, in both scenarios, it makes sense to get back the original number, because 0 equal parts and zero inches wide leaves the original pizza untouched
To illustrate why it’s not the original number, ask yourself this question — “How many times can you slice a pizza such that each slice is 0 inches wide?”
Yes, you’re leaving the pizza untouched with each slice, so you will never stop slicing. Or, you will say zero, because slices that are 0 inches wide are not slices at all. Or you’ll just say it can’t be done.
