Show answer & explanation
Correct answer: D
Align the numbers before subtracting:
1101101
- 0101011
= 1000010
Decimal cross-check:
1101101₂ = 64 + 32 + 8 + 4 + 1 = 109
101011₂ = 32 + 8 + 2 + 1 = 43
109 - 43 = 66
66 in binary is 1000010₂.
Therefore, A - B = 1000010, so the correct answer is Option D.
