1. A biologist counted the number of two types of salmon (Chinook and Steelhead) at a dam. He used the table below to record the number of Salmon on different days. On day 5, the biologist counted 16 Chinook. If the ratio of Chinook to Steelhead remained the same as on the previous four days, how many Steelhead should the biologist expect to count on day 5? Record your answer in the table below.
