To convert a binary number to a decimal number, we can use the place value system. Each digit in the binary number represents a power of 2, starting from the rightmost digit.

Let's break down the given binary number (1101101.1011)2 into its decimal equivalent:

Starting from the rightmost digit, we have:

1 * 2^0 = 1 1 * 2^1 = 2 0 * 2^2 = 0 1 * 2^3 = 8 1 * 2^4 = 16 0 * 2^5 = 0 1 * 2^6 = 64

For the fractional part, starting from the leftmost digit after the decimal point, we have:

1 * 2^-1 = 0.5 0 * 2^-2 = 0 1 * 2^-3 = 0.125 1 * 2^-4 = 0.0625

Now, let's add up all the values:

1 + 2 + 0 + 8 + 16 + 0 + 64 + 0.5 + 0 + 0.125 + 0.0625 = 109.6875

Therefore, the correct answer is D) 109.6875.

To find the 9's complement of a number, we subtract each digit from 9.

Given the number is 33, we can find its 9's complement as follows:

The first digit of the number is 3. To find its 9's complement, we subtract 3 from 9: 9 - 3 = 6.

The second digit of the number is also 3. Again, we subtract 3 from 9: 9 - 3 = 6.

Therefore, the 9's complement of 33 is 66.

Option C) 66 is the correct answer.
