The BCD equivalent of the decimal number 1247 is?

To convert the decimal number 1247 into its Binary-Coded Decimal (BCD) equivalent, we must first understand how BCD represents decimal digits. In BCD, each decimal digit is represented by its own four-bit binary equivalent.

The decimal number 1247 consists of the digits 1, 2, 4, and 7. We convert each digit to binary as follows:

• The digit 1 in binary is 0001.
• The digit 2 in binary is 0010.
• The digit 4 in binary is 0100.
• The digit 7 in binary is 0111.

When we put together these four binary representations corresponding to each digit, we get:

1. 0001 (for 1)
2. 0010 (for 2)
3. 0100 (for 4)
4. 0111 (for 7)

Thus, the complete BCD representation of the decimal number 1247 is 0001 0010 0100 0111. This matches the first choice given. This representation formats each decimal digit separately in binary, making it a clear and unambiguous method for digital systems to process decimal values, which is the essence of
