The numbers used are 0, 1, 2, ... , 15. However, the numbers 10 to 15 are denoted by A, B, C, D, E and F.
This is to distinguish between, for example, the decimal 11 and the hex 11. The latter is 1*161 + 1 (in decimal) or 17 (in decimal).

0xff = 16 x 15 + 15 = 255 The letters A-F are used to represent the decimal numbers 10-15 (respectively) which are required to be held in one hexadecimal digit.
I assume the number is in binary. Separate the binary number from the right, 4 digits at a time: 1011 1011. Then convert each group of four binary digits to hexadecimal. In this case, 1011 is B, so the answer is 0xBB (the prefix 0x is often used to indicate hexadecimal).I assume the number is in binary.

Try it out, and see whether you get the correct results. (You won't.) The difference is that hexadecimal is based on the number 16, and 16 is a power of 2. On the other hand, 10 is NOT a power of 2.
