Final answer:
The subject of this question is Mathematics. It asks about the ratio of hoverboards to electric scooters in a bike store. Additional information is needed to calculate the ratio.
Step-by-step explanation:
The question is asking about the ratio of hoverboards to electric scooters in a bike store. To answer this question, we need more information such as the total number of hoverboards and electric scooters in the store. Once we have that information, we can calculate the ratio by dividing the number of hoverboards by the number of electric scooters. For example, if there are 20 hoverboards and 15 electric scooters, the ratio would be 20/15 = 4/3.
