The video tutorial introduces the concept of rates and unit rates, explaining that a rate is a comparison of two quantities with different units, such as dollars per cheeseburger. A unit rate is a rate with a denominator of one, like miles per hour. The tutorial provides examples, including calculating average speed and cost per item, to demonstrate how to find unit rates by dividing the given quantities.

What is a rate?

• A comparison of two quantities with no units

• A comparison of three quantities with different units

• A comparison of two quantities with different units

• A comparison of two quantities with the same units
