\(\frac{5}{17}-\frac{3}{17}\)||\(\frac{2}{17}\)\(\frac{6}{11}-\frac{3}{22}\)||\(\frac{9}{22}\)\(\frac{7}{26}-\frac{3}{13}\)||\(\frac{1}{26}\)\(\frac{16}{21}-\frac{9}{21}\)||\(\frac{1}{3}\)Hướng dẫn giải:\(\frac{5}{17}-\frac{3}{17}=\frac{2}{17}.\)
\(\frac{6}{11}-\frac{3}{22}=\frac{12}{22}-\frac{3}{22}=\frac{9}{22}.\)
\(\frac{7}{26}-\frac{3}{13}=\frac{7}{26}-\frac{6}{26}=\frac{1}{26}.\)
\(\frac{16}{21}-\frac{9}{21}=\frac{7}{21}=\frac{1}{3}.\)
