# Question: hi i am just going over some maths work that...

###### Question details

Hi, I am just going over some maths work that I have done recently, and I can't seem to get the correct answer for these questions. The first one, I can't remember what to do since my working out comes to a negative answer, and the second one, I am not sure on how I should proceed. Any help would be appreciated. Thanks.
