\(\frac{15}{16}=\frac{8}{16}+\frac{4}{16}+\frac{2}{16}+\frac{1}{16}=\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\)
Ta thấy:
15/16 = 1/16+(1/16+1/16)+(1/16+1/16+1/6+1/16)+(1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16)
=1/16+2/16+4/16+8/16 =1/16+1/8+1/4+1/2
Ta thấy:
15/16 = 1/16+(1/16+1/16)+(1/16+1/16+1/6+1/16)+(1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16)
=1/16+2/16+4/16+8/16
=1/16+1/8+1/4+1/2
\(\frac{15}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)
15 / 16 = 1 / 8 + 1/2 + 1/4 + 1/ 16
tích đúng cho mình nha
\(\dfrac{11}{16}\) = \(\dfrac{1}{16}\) + \(\dfrac{10}{16}\) = \(\dfrac{1}{16}\) + \(\dfrac{2+8}{2\times8}\) = \(\dfrac{1}{16}\) + \(\dfrac{2}{2\times8}\) + \(\dfrac{8}{2\times8}\) = \(\dfrac{1}{16}\) + \(\dfrac{1}{8}\)+ \(\dfrac{1}{2}\)
\(\dfrac{5}{12}\) = \(\dfrac{1}{12}\) + \(\dfrac{4}{12}\) = \(\dfrac{1}{12}\) + \(\dfrac{4}{3\times4}\) = \(\dfrac{1}{12}\) + \(\dfrac{1}{3}\)
\(\frac{15}{16}=\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\)
\(\frac{16}{17}=\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+\frac{1}{272}\)
16/17=1/2+1/4+1/8+1/16+1/272
