`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`

mik ko biết
mong bn thông cảm
nha ................
\(\frac{5}{6}=\frac{1}{6}+\frac{4}{6}=\frac{1}{6}+\frac{2}{3}\) 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 \(\frac{7}{12}=\frac{3}{12}+\frac{4}{12}=\frac{1}{4}+\frac{1}{3}\).......
\(\dfrac{7}{12}=\dfrac{3}{12}+\dfrac{4}{12}=\dfrac{1}{4}+\dfrac{1}{3}\)
\(\dfrac{13}{27}=\dfrac{9}{27}+\dfrac{4}{27}=\dfrac{1}{3}+\dfrac{4}{27}\)
\(\dfrac{7}{12}\) = \(\dfrac{1+6}{12}\) = \(\dfrac{1}{12}\) + \(\dfrac{6}{12}\) = \(\dfrac{1}{12}\) + \(\dfrac{1}{2}\)
\(\dfrac{7}{12}\) = \(\dfrac{3+4}{12}\) = \(\dfrac{3}{12}\) + \(\dfrac{4}{12}\) = \(\dfrac{1}{4}\) + \(\dfrac{1}{3}\)
\(\dfrac{13}{27}\) = \(\dfrac{1+12}{27}\) = \(\dfrac{1}{27}\) + \(\dfrac{12}{27}\) = \(\dfrac{1}{27}\) + \(\dfrac{4}{9}\)
\(\dfrac{13}{27}\) = \(\dfrac{4+9}{27}\) = \(\dfrac{4}{27}\) + \(\dfrac{9}{27}\) = \(\dfrac{4}{27}\) + \(\dfrac{1}{3}\)
\(\dfrac{13}{27}\) = \(\dfrac{6+7}{27}\) = \(\dfrac{6}{27}\) + \(\dfrac{7}{27}\) = \(\dfrac{2}{9}\) + \(\dfrac{7}{27}\)
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
