15 in the hexadecimal number system is represented by 21 in the decimal system.
The answer is 15.

In hexadecimal, the letter "h" does not represent a numerical value. Instead, hexadecimal uses the digits 0-9 and the letters A-F (or a-f) to represent values from 0 to 15. Specifically, A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15. Since "h" is not part of the hexadecimal system, it has no numerical equivalent in that context.
15 base 10 equals F base 16
The number 249 in hexadecimal would be F9. The digits in base 16 correspond to powers of 16 rather than 10. For a two-digit number, the place values are 16 and 1, and the usable values are from 0 to 15, with values 10 through 15 represented by letters A (10) through F (15). F9 = (15x16) + (9x1) = 240 + 9
F. Numbers in hecadecimal start 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10, 11, 12, ...
The answer is 15.
The largest three-digit number in base sixteen (hexadecimal) is FFF. In hexadecimal, each digit can represent values from 0 to 15, with F representing 15. Therefore, FFF in base sixteen is equal to (15 \times 16^2 + 15 \times 16^1 + 15 \times 16^0), which calculates to 4095 in decimal.
111111 in binary is 255 in decimal which is FF in hexadecimal (i.e. 15 units and 15 16s)

The hexadecimal system requires 15 symbols. 0-9 provide 10, so 5 more, different symbols are needed: hence A to E. They could equally well have been £,%,t,# and ].

Hexadecimal is a number system whoose base has 16 numbers. Hexadecimal is usually represented as 0 through 9 and A through F. An example of counting from 9 to 33 follows. 9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21
15 base 10 equals F base 16
Mnemonics is a method of remembering things by associascation. Hexadecimal is a number system. 0-9 are as usual and then a(10) b(11) c(12) d(13) e(14) f(15)
The number 249 in hexadecimal would be F9. The digits in base 16 correspond to powers of 16 rather than 10. For a two-digit number, the place values are 16 and 1, and the usable values are from 0 to 15, with values 10 through 15 represented by letters A (10) through F (15). F9 = (15x16) + (9x1) = 240 + 9
