how do I write this out?

Question

I'm trying to help my daughter out with these 2 problems. I've been out of school for over 20 yrs and so I'm not really sure how to do this. I know it's easy for a lot of you but when your a parent that doesn't use this every day it's a bit confusing. Thank you for your help.
