**Answer:**

<u>**Signed:**</u> -4 -5 +6 -1

<u>**Unsigned:**</u> 12 13 6 9

**Explanation:**

We are given with binary number i.e. 1100110101101001. First of all we will break this binary number into sets of 4 starting from the right side of the binary number. First set will be **1001**, second will be **0110**, third wil be **1101**, fourth will be **1100**.

<u>**Basic concept of converting binary numbers into decimal numbers:**</u>

256 128 64 32 16 8 4 2 1

0 1 1 0 1 0 0 1 1

Add the number written above each of the binary number if its 1 and ignore if its 0. Starting from the left side 0 represents 256 so, we will ignore it. 1 represents 128 so we will consider it and so on.

128+64+16+2+1 = 211

011010011 is the binary of 211.

**For signed binary**, if the last number of the set is 0 the, it is a postive number. **For unsigned binary**, if the last number of the set is negative then, it is a negative number.

<u>**For signed binary:**</u>

1100 1101 0110 1001

-4 -5 +6 -1
