I know nothing about networking. I was asked to find a percentage of all packets that are broadcast packets from a capture I did. Can someone tell me how to do that please?

Maybe you might want to look for packets that have either a MAC address of FF:FF:FF:FF:FF:FF or an IP address of - but that might not include all broadcast messages, because for that you would need to know all subnets and subnets masks to be able to determine what the broadcast address of a subnet is. For example could be a broadcast if the network is, but if it is it isn't.

By the way, this looks like a lot of questions coming from some sort of homework assignment, so if that is the case I would advise you to study and find the answers for yourself ;-)
