Assigning IP's to multiple LAN network

[Moonman131]

I have an assignment, to assign IP's to LAN networks(Network address, first and last host and broadcast)

I have started doing the assignment(pic attached) but I have no idea if I'm doing it correctly I'm new to networking and our professor told us not to us "subnetting" as we have not learned that yet. did I assign the IP correctly? and if not how would I have done it? Thank you!

We don't do homeworks here.

I'm not asking for HW solution.
I'm wondering if I'm on the right track, a simple yes/no answer will do 😀
Note: updated with more work
I'm aware that Routers have no IP assigned aswell as that mask is incorrect. but is the rest of part correct?

Your broadcast addresses are all wrong! Read some books!!

Your addressing is not correct based on the CIDR that you are using. If you have learned subnet masks, that will help you to identify what is wrong with your subnets.

Not even close, how can you have the same network address on all the networks, I presume the 172.185.0.0 /24 was given to you on LAN 16? It is impossible to have a 192.168.x.x on that segment. Are the switches flat or managed? It looks like you are just guessing in which case I wish you all the luck in the world!

I don't get the assignment. "Don't use subnetting", but use routers? What? How does that make any sense? I feel like I'm missing something.
