Convert (15)10 to hexadecimal

  • A.E
  • B.IF
  • C.F
  • D.10

Answer: C

(15)10 in hexadecimal is F.

Hexadecimal uses sixteen digits: 0 to 9 for zero to nine, then A, B, C, D, E and F for ten to fifteen. Fifteen is less than sixteen, so it needs only one hexadecimal digit, and that digit is F.

E is fourteen. 10 in hexadecimal is sixteen (one sixteen and no units). 'IF' is not a hexadecimal numeral, since I is not a hexadecimal digit; 1F would be thirty-one.
