Work Step by Step
$11010.1101_2$
$=1\times2^4+1\times2^3+0\times2^2+1\times2^1+0\times2^0+1\times\frac{1}{2}+1\times\frac{1}{4}+0\times\frac{1}{8}+1\times\frac{1}{16}$
$=16+8+0+2+0+\frac{1}{2}+\frac{1}{4}+0+\frac{1}{16}$
$=16+8+0+2+0+\frac{8}{16}+\frac{4}{16}+0+\frac{1}{16}$
$=26\frac{13}{16}=26.8125$
