\(\frac{15}{16}\)= \(\frac{1}{16}\)+ \(\frac{1}{8}\)+ \(\frac{1}{4}\)+ \(\frac{1}{2}\)

P/s tham khảo nha

\(\frac{15}{16}+\frac{1}{16}+\frac{1}{8}+\frac{1}{2}+\frac{1}{4}\)

\(\dfrac{15}{16}=\dfrac{1}{16}+\dfrac{1}{8}+\dfrac{1}{4}+\dfrac{1}{2}\)

\(\frac{13}{16}=\frac{1}{2}+\frac{1}{4}+\frac{1}{16}\)

Ta có:\(\frac{13}{16}=\frac{1+4+8}{16}=\frac{1}{16}+\frac{1}{4}+\frac{1}{2}\)

Ta có:\(\frac{15}{16}=\frac{1}{16}+\frac{2}{16}+\frac{4}{16}+\frac{8}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)

Bấm đúng nếu thấy đúng!thanks

chị có thể noí rõ hơn ko em vẫn ko hiểu

=1/3+1/4

\(\dfrac{7}{8}=-\dfrac{1}{8}+1\)

7/8=1/2+ 1/4+1/8

Phân tích: 
15/16= 1/16+ 2/16 + 4/16 + 8/16= 1/16+1/8+1/4+1/2 
Vậy: 15/16= 1/16+1/8+1/4+1/2 

vì 16 chia hết cho 1, 2,4,8 nên ta có thể phs như sau:

\(\frac{15}{16}=\frac{1+2+4+8}{16}=\frac{1}{16}+\frac{2}{16}+\frac{4}{16}+\frac{8}{16}=\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)\( +\frac{1}{2}\)
