Correct:
B
Explanation
To convert the hexadecimal number A53.8 to its decimal equivalent, we calculate the sum of each digit multiplied by its corresponding power of 16:
- A (which represents 10 in decimal) × 162 = 10 × 256 = 2560
- 5 × 161 = 5 × 16 = 80
- 3 × 160 = 3 × 1 = 3
- 8 × 16-1 = 8/16 = 0.5
Adding these components together: 2560 + 80 + 3 + 0.5 = 2643.5.
In the provided options, the hyphen '-' is used in place of a decimal point. Thus, 2643.5 is represented as 2643-5. Options A, C, and D do not match the calculated value.
