Question 1: Convert 10010001 from unsigned binary to hexadecimal.
To convert a binary number to a hexadecimal number, we can use the following steps:
Step 1: Group the binary number into sets of 4 bits, starting from the rightmost bit. If there are any remaining bits, add zeros to the left.
In this case, we have 10010001, which can be grouped as 0001 0010 0001.
Step 2: Convert each group of 4 bits into its hexadecimal equivalent.
The hexadecimal equivalents for each group are as follows:
- 0001 = 1
- 0010 = 2
- 0001 = 1
So, the hexadecimal representation of 10010001 is 121.
Step 3: Verify the answer.
To verify the answer, we can convert the hexadecimal number back to binary and check if it matches the original binary number.
Converting 121 to binary, we get 0001 0010 0001, which is the same as the original binary number 10010001.
Therefore, the correct answer is option 'B' (91).
