At Zane's car lot, 5/6 of the cars sold were blue. Across the street, 1/6 of the cars sold at Luna's car dealership were blue. Which business sold a greater fraction of blue cars?
5/6 is greater than 1/6 , but if their businesses are different sizes it could matter. 5/6 of a small business could be less than 1/6 of a huge business.
