Hello!
If the signs are the same, and you multiply or divide, the sign of the product or quotient will be positive. If the signs are different, the product or quotient will be negative.
It is! When you're doing a fraction specifically like that, the denominators cancel out. Therefore you can get rid of the 12. It just becomes 21/7, which as you know is 3.
Hope that helps :)

15) Since w = 23, w + 45 = 68
