\(\Large \dfrac{8}{10}\) \(\Large \dfrac{6}{10}\) \(\Large \dfrac{8}{1

• A.

   \(\Large \dfrac{8}{10}\)

• B.

   \(\Large \dfrac{6}{10}\)

• C.

   \(\Large \dfrac{8}{15}\)

• D.

   \(\Large \dfrac{15}{20}\)

 \(\Large \dfrac{8}{10} = \dfrac{8 : 2}{10 : 2} = \dfrac{4}{5}\)

\(\Large \dfrac{6}{10} = \dfrac{6 : 2}{10 : 2} = \dfrac{3}{5}\)

\(\Large \dfrac{15}{20} = \dfrac{15 : 5}{20 : 5} = \dfrac{3}{4}\)

Vậy  \(\Large \dfrac{4}{5} = \dfrac{8}{10}\)
