These are school homework questions, aren't they. You need to look up all the numeric functions, such CEIL.
And if you want to get good marks, do not use "record" when you mean "row".

I notice that you repeatedly raise topics with titles such "SQL help". This is stupid. It makes your questions effectively un-searchable. Please use proper titles if you want help in future.
