title: convert decimal numbers to excess-127 representations
body: <p>Represent the following decimal numbers in binary using 8-bit signed magnitude, one’s complement, two’s complement, and excess-127 representations.</p>
  
  <p>a) 77</p>
  
  <p>b) –42</p>
  
  <p>c)  119</p>
  
  <p>d)  –107</p>
  
  <p>I've converted them to the other representations just need to know how to convert to excess-127</p>
  
  <p>a) Signed magnitude: 01001101 
  One's complement: 01001101
  Two's complement: 01001101 </p>
  
  <p>b) Signed magnitude: 10101010
  One's complement: 11010101 
  Two's complement: 11010110 </p>
  
  <p>c) Signed magnitude: 01110111 
  One's complement: 01110111 
  Two's complement: 01110111 </p>
  
  <p>please help</p>
