    A selling factor for auto makers is mpg (miles per gallon). A new Toyota is hyped to get 45 mpg, which is a rate. As a ratio, it can be represented as 45:1 or 45 miles to 1 gallon. This can be expanded onto a table with 2 columns, one for gallons and one for miles. From here you can ask questions like how many miles can you go with 9 gallons of fuel?

    These are so intertwined, it’s easy to see how we get lost. I think I’m getting better at separating the different parts.
