\(\frac{16}{21}=\frac{1}{7}+\frac{13}{21}=\frac{1}{21}+\frac{5}{7}\)
\(\frac{13}{14}=\frac{5}{7}+\frac{3}{14}=\frac{1}{2}+\frac{3}{7}\)
\(\frac{1}{3}\)\(\frac{1}{3}\)\(\frac{1}{3}\)1/3+3/7
9/14+4/14
ta có:
16/21=16.14/21.14
=224/294
13/14=13.21/14.21
=273/294
vậy hai phân số đó là:
274/294 và 273/294
\(\frac{16}{21}\)=8/21+8/21
\(\frac{13}{14}\)=1/14+ 3/14+ 9/14

\(\frac{16}{21}\) = \(\frac{1}{7}\) + \(\frac{13}{21}\) = \(\frac{1}{21}\) + \(\frac{5}{7}\)
\(\frac{13}{14}\) = \(\frac{5}{7}\) + \(\frac{3}{14}\) = \(\frac{1}{2}\) + \(\frac{3}{7}\)
