1. The problem statement, all variables and given/known data Write all the possible decimal values (3 of them) of the 8-bit hexadecimal number 0xD1. 3. The attempt at a solution So I can write that D1 = D*161 + 1 * 160 = 13*16 + 1 = 209 Can I also say that the most significant bit is reserved for sign? In that case, I think the D would indicate a negative value (is that right? What's the cutoff for positive/negative signed values in hexadecimal?) Thus, I would have: - (1 * 160) = -1 The only other interpretation I can think of is to say that D1 is a complement, so I'd have to convert to binary and then convert to decimal. So: D1 = 1101 0001, then I take all the places where the value is zero and add. Doing so gives: 2 + 4 + 8 + 32 = 46 I also have to add one to 46, I believe. So my answer is 47. Is that so?
