Answer 2

Answer:

2's complement of 11001011 is 00110101.

Explanation:

• In context to the give question we have to find the 2’s complement of 11001011.

Given :-

Binary number is 11001011

Solution :-

we know that,

2's complement of a binary number = 1's complement of the binary number + 1

To solve the question,

we should know 1's complement of the binary number.

⇒ 1's complement of the 11001011 = simply invert of the number

i.e. 00110100

now putting it in the formula , we get

2's complement of 11001011 = 1's complement of 11001011 + 1

2's complement of 11001011 = 0110100 +1 = 00110101.

Therefore, 2's complement of 11001011 is 00110101.
