1. True
2. b
3. Size the add_unsigned, add_signed, and mult signals:

   logic unsigned [8:0] add_unsigned;
   logic signed [8:0] add_signed;
   logic unsigned [15:0] mult;
   

4. If you use fixed point notation, which we will discuss in Chapter 7, Math, Parallelism, and Pipelined Design, you can calculate the fractional value, i.e., 1/n, and then multiply by the calculated value.
