\(\Large \dfrac{10}{15}\) \(\Large \dfrac{12}{16}\) \(\Large \dfrac{20

• A.

  \(\Large \dfrac{10}{15}\)

• B.

  \(\Large \dfrac{12}{16}\)

• C.

  \(\Large \dfrac{20}{15}\)

• D.

  \(\Large \dfrac{6}{9}\)

\(\Large \dfrac{10}{15} = \dfrac{10 : 5}{15 : 5} = \dfrac{2}{3}\)

\(\Large \dfrac{12}{16} = \dfrac{12 : 4}{16 : 4} = \dfrac{3}{4}\)

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

\(\Large \dfrac{6}{9} = \dfrac{6 : 3}{9 : 3} = \dfrac{2}{3}\)

Vậy ta chọn phân số \(\Large \dfrac{12}{16}\).
