\(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{6}+\frac{1}{64}+\frac{1}{128}\)
\(=\frac{64}{128}+\frac{32}{128}+\frac{16}{128}+\frac{2}{128}+\frac{1}{128}+\frac{1}{6}\)
\(=\frac{115}{128}+\frac{1}{6}\)
\(=\frac{409}{384}\)
1/2 + 1/4 + 1/8 + 1/6 + 1/64 + 1/128
=64/128 + 32/128 + 16 / 128 + 2/128 + 1/128
=115/128
