Answer :

In the hexadecimal numbering system, the number 69 is equivalent to the decimal number 105. The value of f is therefore calculated by subtracting 105 from 127, which is the largest possible value in one byte of data. Therefore, the value of f is 22 (127 - 105 = 22).

In summary, 69 is a hexadecimal representation of the decimal number 105, and f is the difference between 127 (the maximum value in one byte of data) and 105. Understanding hexadecimal and binary numbering systems is essential in the field of computer science and programming.
To find the value of "f" in the equation 69 = 7f, follow these steps:

Step 1: Identify the given equation, which is 69 = 7f.

Step 2: Notice that you need to find the value of "f" and the equation shows that it is multiplied by 7.

Step 3: To isolate "f" and find its value, you need to perform the inverse operation, which in this case is division.

Step 4: Divide both sides of the equation by 7: (69 = 7f) / 7.

Step 5: Perform the division: 69 / 7 = 7f / 7.

Step 6: Simplify the equation: 9.857 = f.

So, the value of "f" is approximately 9.857.

The value of f is : f = 9.8571.

To find the value of f in the equation 69 = 7f, follow these steps:

  1. Start by isolating f by dividing both sides of the equation by 7:

    [tex]\frac{69 }{7} = \frac{7f} { 7}[/tex]

  2. This simplifies to:

    9.8571 = f
