Explanation:

The binary digits are grouped into sets of four, and each group is then converted straight to its hexadecimal equivalent in order to convert a binary number (base 2) to a hexadecimal number (base 16). One hexadecimal digit is equivalent to four binary digits, so this works.

Steps for Binary to Hexadecimal Conversion:

  1. Start with the binary number.
    • For example: 110101111.
  2. Group the binary digits into sets of 4, starting from the right.
    • Add leading zeros if necessary to ensure all groups have 4 digits.
    • Example: 110101111 → 000110101111 → 0001 ∣ 1010 ∣ 1111
  3. Convert each group of 4 binary digits into its hexadecimal equivalent.
    • 0001 → 1
    • 1010 → A
    • 1111 → F
  4. Combine the hexadecimal digits.
    • 1AF (this is the hexadecimal representation).
