A. -27
Magnitude: 00011011
Since the sign is negative add 1 to the MSB
which becomes 100011011
B. 140
Magnitude: 10001100
Since the sign is positive add 0 to the MSB
which becomes 010001100
C. -99
Magnitude: 01100011
Since the sign is negative add 1 to the MSB
which becomes 101100011
D. 46
Magnitude: 00101110
Since the sign is positive add 0 to the MSB
which becomes 000101110
