For 4A9.2B:
Integer part: 4A9 = 4 * 16^2 + A (10) * 16^1 + 9 * 16^0
= 4 * 256 + 10 * 16 + 9 * 1
= 1024 + 160 + 9 = 1193
Fractional part: .2B = 2 * 16^-1 + B (11) * 16^-2
= 2 / 16 + 11 / 256
= 1 / 8 + 11 / 256
= 32 / 256 + 11 / 256 = 43 / 256
Convert 43/256 to decimal: 43 ÷ 256 ≈ 0.16796875
Combining the integer and fractional parts: 1193 + 0.16796875 = 1193.16796875. This matches option A when rounded to four decimal places.
