Answer 1

[Nguyễn Lê Phước Thịnh]

\(\dfrac{26}{8}-\dfrac{9}{4}=\dfrac{13}{4}-\dfrac{9}{4}=\dfrac{4}{4}=1\)

\(\dfrac{7}{5}-\dfrac{15}{25}=\dfrac{35}{25}-\dfrac{15}{25}=\dfrac{20}{25}=\dfrac{4}{5}\)

\(\dfrac{5}{9}-\dfrac{6}{27}=\dfrac{5}{9}-\dfrac{2}{9}=\dfrac{3}{9}=\dfrac{1}{3}\)

Answer 2

[456]

\(\dfrac{26}{8}-\dfrac{9}{4}=\dfrac{26}{8}-\dfrac{18}{8}=1\)

\(\dfrac{7}{5}-\dfrac{15}{25}=\dfrac{35}{25}-\dfrac{15}{25}=\dfrac{20}{25}=\dfrac{4}{5}\)

\(\dfrac{5}{9}-\dfrac{6}{27}=\dfrac{15}{27}-\dfrac{6}{27}=\dfrac{9}{27}=\dfrac{1}{3}\)
