\(\frac{15}{16}=\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+....+\frac{1}{16}\) (15 SỐ HẠNG)
\(\frac{1}{2}\)+\(\frac{1}{4}\)\(\frac{1}{16}\)+\(\frac{1}{16}\)+\(\frac{1}{16}\)
Ta có: \(\frac{15}{16}=\frac{1}{16}+\frac{8}{16}+\frac{4}{16}+\frac{2}{16}\)
Lại có: \(\frac{8}{16}=\frac{1}{2}\)
\(\frac{4}{16}=\frac{1}{4}\)
\(\frac{2}{16}=\frac{1}{8}\)
\(\Rightarrow\frac{15}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)
\(\frac{15}{16}=\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\)
