How to display an infinite ratio to best communicate that the set contains exclusively one type?

I have a reporting dashboard displaying a ratio of apples to oranges normalized to 1:x such as 10 apples and 20 oranges is "1:2".

How would I best display 0 apples 20 oranges?

• "1:Infinity" is an option but looks weird
• "0:20" or "0:1" shouldn't be options due to the requirement of normalizing it in the form of "1:x", but really the intent is to communicate to the user that for this cell of the table there are "only oranges"
