Based on the ratio of Chinooks to Steelhead, if there are 120 Steelheads, the biologist should expect to count 48 Chinooks.

How many Chinooks will the Biologist find?

The first part of the question shows that for every 4 Chinooks, there are 10 Steelheads.

The ratio of Chinooks to Salmon is therefore:
= 10 / 4

= 2.5

This means that for every 1 Chinook, there are 2.5 Steelhead.

If there are 120 Steelheads, the number of Chinooks would be:

= 120 / 2.5

= 48 Chinooks
