There are 40,000 people in your entire target audience (males 20-25).
Each episode of Program A has 5,000 viewers from your target audience (males 20-25).
This means that the REACH for one episode is 5,000.
It also means that the RATING for Program A, for your target audience (males 20-25) = 5,000/40,000 = 12.5% or 12.5.
In other words, when calculating for ONE episode: Rating = Reach (for one show) / Target
Note: As you learned in Chapter 9, rating is a percent, but it is not expressed that way (e.g. a rating of 10 = 10%).
Program B has a Rating of 10% or 10.
