Work Step by Step
$1.11111_2$
$=1\times2^0+1\times\frac{1}{2}+1\times\frac{1}{4}+1\times\frac{1}{8}+1\times\frac{1}{16}+1\times\frac{1}{32}$
$=1+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+\frac{1}{32}$
$=1+\frac{16}{32}+\frac{8}{32}+\frac{4}{32}+\frac{2}{32}+\frac{1}{32}$
$=1\frac{31}{32}=1.96875$
