Explanation / Answer
17. First, we should take a positive decimal number 1 in the binary form which is 00000001. And then we should take one's complement of that number which is 11111110. By adding 1 to that one's complement we will get the two's complement of the number which is a negative number in decimal form. We get 11111111 as two's complement to 00000001. In this way, we convert the decimal negative numbers into the binary form.
18. This is also in the same as above one.At first, the binary form of positive 2 is 00000010. one's complement is 11111101. We will get two's complement by adding 11111101 + 1 i.e., 11111110. Therefore, the binary form of -2 is 11111110
19. This is also in the same as above one. At first, the binary form of positive 3 is 00000011. one's complement is 11111100. We will get two's complement by adding 11111100 + 1 i.e., 11111101. Therefore, the binary form of -3 is 11111101.
20. This is also in the same as above one.At first, the binary form of positive 4 is 00000100. one's complement is 11111011. We will get two's complement by adding 11111011 + 1 i.e., 11111100. Therefore, the binary form of -4 is 11111100
