Workbook pages

I'm kind of new to Excel and what i do know is self taught. I've created a spreadsheet of several pages which is a price list. I've split the pages (so it's A4 size but split into two so when it's printed it will be folded in half to create an A5 size booklet). My problem is i want to number the pages so a contents page can be include. When i go to print preview it shows 55 pages. How do i delete the blank pages i don't want. I tried just deleting rows but that doesn't seem to work. Can anyone help?
