1101 binary= 13 in decimal.
and after the decimal point.
101 = (1*(1/2power1)) + (0*(1/2power2)) + (1*(1/2power3)).
= (1/2 + 1/8),
= (4+1)/8,
= 5/8,
= 0.625.
and after the decimal point.
101 = (1*(1/2power1)) + (0*(1/2power2)) + (1*(1/2power3)).
= (1/2 + 1/8),
= (4+1)/8,
= 5/8,
= 0.625.

1*2^1=1/2,
1*2^2=0,
1*2^3=1/8,
1/2+0+1/8 = 625.
1*2^2=0,
1*2^3=1/8,
1/2+0+1/8 = 625.

It's wrong method.
Because the Binary form is in sequence so Please Explain in detail.

1(1÷2^1)+1(1÷2^2)+1(1÷2^3)=(1÷2)+(1÷8)=0.625.

@Seenu147.
8 + 4 + 0 + 1 = 13.
8 + 4 + 0 + 1 = 13.

Why we can't use 8421 which means in this problem 1101-> 8 + 4 + 0 + 1=15.

Thanks for explaining the solution.

Because after decimal negative power starts. So when you convert a binary no having a decimal point then you have to multiply by 2^(negative power starts from -1 rather than 1).
