Sửa lại cho mình \(\frac{1}{12}\)thành \(\frac{1}{2}\)nhé !
\(\frac{15}{16}=\frac{1}{16}+\left(\frac{1}{16}+\frac{1}{16}\right)+\left(\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}\right)\)\(+\left(\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}+\frac{1}{16}\right)\)\(=\frac{1}{16}+\frac{2}{16}+\frac{4}{16}+\frac{8}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)

15 / 16 = 1 / 8 + 1/2 + 1/4 + 1/ 16
tích đúng cho mình nha
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
\(\frac{15}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)
câu 1 15/16= 1/16+[1/16+1/16]+[1/16+1/16+1/16+1/16]+[1/16+1/16+1/16+1/16+1/16+1/16+1/16+1/16]
=1/16+1/2+1/4+1/8
15/16 = 1/8 + 1/2 + 1/4 + 1/16.
