Answer

a)  signed magnitude representation of 77 is 01001101

     1's complement representation of 77 is 01001101

     2's complement representation of 77 is 01001101   

b)  signed magnitude representation of -42  is 10101010

     1's complement representation of -42 is 11010101

     2's complement representation of -42 is 11010110  

c)  signed magnitude representation of 119 is 01110111

     1's complement representation of   119 is 01110111

     2's complement representation of    119 is 01110111
