Answer:

6in

Step-by-step explanation:

Let's organize what we know.

- 5gal/1in

- 30gal tank

Since we need to find the inches of the fish he can have, we can set up a proportion like this:

5/1=30/x

We can cross multiply.

5x=1(30)

Simplify: 1*30=30

5x=30

Now we can isolate the variable.

5x=30

/5   /5

x=6
