\(\frac{31}{32}\)= \(\frac{1+2+4+8+16}{32}\)= \(\frac{1}{32}\)+ \(\frac{2}{32}\)+ \(\frac{4}{32}\)+ \(\frac{8}{32}\)+ \(\frac{16}{32}\)= \(\frac{1}{32}\)+ \(\frac{1}{16}\)+ \(\frac{1}{8}\)+ \(\frac{1}{4}\)+ \(\frac{1}{2}\)
Vậy \(\frac{31}{32}\)= \(\frac{1}{32}\)+ \(\frac{1}{16}\)+ \(\frac{1}{8}\)+ \(\frac{1}{4}\)+ \(\frac{1}{2}\)
\(\frac{31}{32}=\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+\frac{1}{32}\)
