Which of these is a unit rate? 3 hotdogs for 6 cupcakes

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a single unit. In your example, "3 hotdogs for 6 cupcakes," you can find the unit rate by dividing both quantities to express the relationship in terms of one item. To find the unit rate of hotdogs per cupcake, you would divide the number of hotdogs by the number of cupcakes: \[ \text{Unit rate} = \frac{3 \text{ hotdogs}}{6 \text{ cupcakes}} = \frac{1}{2} \text{ hotdog per cupcake} \] So, the unit rate is \( \frac{1}{2} \) hotdog per cupcake.
