- $1 \ast 22 + 1 \ast 21 + 0 \ast 20 + 1 \ast 2^{-1} + 0 \ast 2^{-2} + 1 \ast 2^{-3} = 6.625$
- $1118 \mod 16 = 14,$ quotient $= 69$
$\qquad 69 \mod 16 = 5,$ quotient $= 4$
$\qquad 4 \mod 16 = 4.$
Writing the mods in the reverse order (in hex) gives $(45E)_{H}.$
Both can be done using a calculator also.
