Binary code BCD code both are different, in binary it is 00101011, but in BCD it is 0100 0011.

In hexa the given decimal number should be divided by 16 (in 43 it has 2 as a quotient) and the remainder should be converted to direct Hexa equivalent number (in here it is 11 it's equivalent hexa number is B).

So, combining these we get {2B}.

43/16 =2.
16*2 =32.
therefore 43-32 =11.

Then we will convert 43 to binary number.

43/2 = 21 rem 1 again divide 21 with 2.
21/2 = 10 rem 1.
10/2 = 5 rem 0.
5/2 = 2 rem 1.
2/2 = 1 rem 0.
0101011.
so A=10.
B=11.
And the answer will be 2B, 0101011.

In hexa decimal 43= 2B,
And 43 in BCD presentation 4 = 0100, 3 = 0011.
43 = 01000011
So, the answer is 2B : 01000011.
