Có thể viết như sau:

Ta có:\(\frac{7}{16}=\frac{3}{16}+\frac{4}{16}=\frac{3}{16}+\frac{1}{4}\)

Vậy Phân số \(\frac{7}{16}\)= \(\frac{3}{16}+\frac{1}{4}\)

7/16=2/16+5/16=1/8+5/16

7/16=4/16+3/16=1/4+3/16

\(\dfrac{7}{16}=\dfrac{1+6}{16}=\dfrac{1}{16}+\dfrac{6}{16}=\dfrac{1}{16}+\dfrac{3}{8};\)

\(\dfrac{7}{16}=\dfrac{2+5}{16}=\dfrac{2}{16}+\dfrac{5}{16}=\dfrac{1}{8}+\dfrac{5}{16};\)

\(\dfrac{7}{16}=\dfrac{3+4}{16}=\dfrac{3}{16}+\dfrac{4}{16}=\dfrac{3}{16}+\dfrac{1}{4}\)

`7/12 = 6/12 + 1/12 = 1/2 + 1/12`

`7/12 = 3/12 + 4/12 = 1/4+1/3`

`7/12 =2/12 + 5/12 = 1/6 + 5/12`

\(\dfrac{7}{12}=\dfrac{1}{3}+\dfrac{1}{4}\)

cái này mình suy nghĩ nát óc mới ra nè, bạn xem đúng không

\(\sqrt{ko}234\sqrt[]{56}\)

Lời giải:

$\frac{7}{8}=\frac{1}{8}+\frac{2}{8}+\frac{4}{8}=\frac{1}{8}+\frac{1}{4}+\frac{1}{2}$

1/5 + 4/15

mik ko biết

mong bn thông cảm 

nha ................

7/12 = 1/3 + 1/4

5/6=1/6+2/3

\(\frac{1}{2}+\frac{1}{3}=\frac{5}{6}\)

\(\frac{1}{3}+\frac{1}{4}=\frac{7}{12}\)

Cho xin tk

\(\frac{5}{6}=\frac{1}{6}+\frac{4}{6}=\frac{1}{6}+\frac{2}{3}\) hoặc \(\frac{5}{6}=\frac{2}{6}+\frac{3}{6}=\frac{1}{3}+\frac{1}{2}\)

 \(\frac{7}{12}=\frac{1}{12}+\frac{6}{12}=\frac{1}{12}+\frac{1}{2}\) hoặc \(\frac{7}{12}=\frac{3}{12}+\frac{4}{12}=\frac{1}{4}+\frac{1}{3}\).......
