7.
It is 90
It is five.
To find the 9s complement, subtract each digit from 9: 27 → 72
00110011 is the 2's complement for this unsigned number and 10110011 if this is a signed number
26
The same number of bits are used to represent 1's complement and 2's complement. To take 2's complement, first take the 1's complement, then add 1 to the result.
1's complement numbers are those numbers which are obtain after converting 1 to 0 and 0 to 1. for e.g. 110010 1's complement of this number is:001101 2's complement is obtain by adding 1 in 1's complement of number. for e.g. 2's complement of above number:001101 + 1 --------------- 001110
To find the 2's complement of a binary number, invert all the bits and add 1 to the result.
9s + 7 = -11 9s = -18 s = -18/9 s = -2
It is 99.
9's complement of a decimal number represented in 2421 code is easily obtained by replacing the 1s with 0s,and 0s with 1s,so 2421 code is called a self complementing code.example-2421 of '2' is '0010',after replacing the 0s with 1s and 1s with 0s weget '1101' which is the 2421 of '7'(9s complement of 2 is 7). Thus 2421 code is self complementary.
