Solution
Answer: Option A
Solution:
To convert a hexadecimal number to its decimal equivalent, you need to understand the place values in hexadecimal.
In hexadecimal, the digit positions represent powers of 16, starting from 16^0 on the right.
The number 3F in hexadecimal can be broken down as follows:
3 is in the 16^1 position, so its value is 3 * 16 = 48.
F is in the 16^0 position. In hexadecimal, F equals 15, so its value is 15 * 1 = 15.
Adding these values together gives 48 + 15 = 63.
Therefore, the decimal equivalent of 3FH is 63.
