Question

1.Convert the following decimal number into binary number of:

9
68
987
7636
​

Answer 1

Answer:

9 = (1001)₂

68 = (1000100)₂

987 =  ( 1111011011)₂

7636 = (1110111010100)₂

Step-by-step explanation:

Convert the following decimal number into binary number :

9

68

987

7636

   9

2   4    1

2    2   0

2    1    0

2    0    1

9 = (1001)₂

 68

2 34  0

2  17  0

2  8   1

2  4  0

2  2  0

2  1   0

2   0  1

68 = (1000100)₂

Similarly  987 =  ( 1111011011)₂

7636 = (1110111010100)₂

Answer 2

Answer:

11110000

Step-by-step explanation:

-9-7

(-9)+(-7)

now convert the both into binary numbers by dividing them by 2

(-9)=(-1001)

(-7)=(-111)

convert convert them into 8 digit numbers by adding zero

(-1001)=(-00001001)

(-111)=(-00000111)

now take that 2's complement of both numbers

to take to compliment first take 1's complement of both numbers by doing this we will make the numbers positive

to take one's complement replace the 0s by 1 and 1s by 0

(-00001001)=11110110

(-00000111)=11111000

now take the 2's complement by adding 1 to both the numbers

11110110+1=11110111

11111000+1=11111001

now at the both numbers

11110111+11111001=11110000

thus answer is 11110000
