I assume you mean BCD, Binary Coded Decimal.
BCD uses 4 bits to represent one decimal number.
The easiest way is to make a table, with decimal, BCD, Hex and straight binary.
1 0000 0001 1 0000 0001
2 0000 0010 2 0000 0010
3 0000 0011 3 0000 0011
...Skip a bit....
9 0000 1001 9 0000 1001
10 0001 0000 A 0000 1010
11 0001 0001 B 0000 1011
...Skipping again....
15 0001 0101 F 0000 1111
16 0001 0110 10 0001 0000
Get the idea? In the first one, 4 binary bits are matched with one decimal digit. In straight binary, the number scrolls on.
Interestingly, this caused some problems, earning itself the name 'the 2.1K bug'. some systems, generally small systems like Eftpos terminals, wrote values in BCD binary, but read them as straight binary. So dates were written in BCD 10, but read back as (check the table) Ordinary binary 16. Hilarity ensued.
What else can I help you with?
How does the binary numbering system differ from the hexadecimal numbering system?
the binary system is base 2 and the hexadecimal system is base 16
How does number code differ from a number system?
Number System enables enumeration & quantitation of physical objects. For e.g. Binary, Octal, Decimal & Hexadecimal Number Systems.Number Code encodesunique characters with a number ineach Number System. For e.g.In ASCII Codecapital A is represented as 41 in hexadecimal, 65 in Decimal, 101 in Octal and 01000001 in Binary number System.

Why binary system based on binary number?
Because if it were not, then the name of the system would have to be changed.
What is the decimal number of the binary number 13 in the OCT counting system?
There is no decimal number for the binary number 13 because 13 cannot be a binary number.
