Which is the hex representation of decimal 15?

Explanation:
Hexadecimal uses digits 0-9 and A-F, with each digit representing 4 bits. Decimal 15 is binary 1111, which corresponds to F in hex. When representing a standard 8-bit value, it’s common to use two hex digits, so 15 becomes 0F to fill the byte. 000F would also equal 15, but it’s just a longer, more padded form. F0 equals 11110000 in binary, which is 240 in decimal, and FF is 11111111, which is 255. Therefore, the correct hex representation for decimal 15 in the common two-digit form is 0F.
