1- Calculate the first part (left side of the dot)
$ 1\times 2^{3} + 1 \times 2^{2} + 0 \times 2^{1} + 1 \times 2^{0} = 13$
2- Calculate the second part (right side of the dot)
$ 0 \times 2^{-1} + 0 \times 2^{-2}+ 1\times 2^{-3} = 0.125 $
3- Add numbers calculated in 1 and 2 together (whole number + decimal part)
$ 13 + 0.125 = 13.125$
