    A 16 pound roast will feed 24 people. If the largest roast you can buy is 12 pounds. How many people can you feed?

    Set up a proportion of roast pounds to people fed, where p is the number of people fed on a 12 pound roast:
    16/24 = 12/p

    Run this through our proportion calculator by typing 16/24 = 12/p into our search engine.

    We get p = 18.

    A 12 pound roast will feed 18 people.
