How do I get highest CTR(CTR = clicks/impressions) given columns for clicks and impressions

Occasional Contributor

Given 2 columns with 161 rows of data for clicks and impressions of a campaign, I am trying to find highest ClickThroughRate(CTR=clicks/impressions) of all. How do I do it? 

I am looking for approaches without creating a new column for CTR and running MAX function on it.
