At my age, I'm embarrassed to admit that I can't remember the rules of division (although I've never been good at math). My question is when I'm dividing, how do I know when to add another zero above the dividing bracket? For example, I am converting 104.9 degrees Fahrenheit to Celsius. So to do that, I take 104.9-32=72.9/1.8=40.5C. I know this is the right answer because my book says it is, but the answer I got was 45, because I didn't add another zero above the bracket when I was dividing 72.9 by 1.8 - how do I know when to do this? I know this is elementary, but I can't seem to get it. If someone could explain the rules in easy-to-understand terms, I would appreciate it very much.
