Answer 1

\(\dfrac{9}{25},\dfrac{3}{50}\) và \(\dfrac{16}{75}\) MSC : 150

\(\dfrac{9}{25}=\dfrac{9\times6}{25\times6}=\dfrac{54}{150}\)

\(\dfrac{3}{50}=\dfrac{3\times3}{50\times3}=\dfrac{9}{150}\)

\(\dfrac{16}{75}=\dfrac{16\times2}{75\times2}=\dfrac{32}{150}\)

Answer 2

\(\dfrac{9}{25};\dfrac{3}{50};\dfrac{2}{9}\) ( \(\dfrac{16}{75}=\dfrac{2}{9}\) ) ( MTC: 250 )

\(\dfrac{9}{25}=\dfrac{9\times18}{25\times18}=\dfrac{162}{450}\)

\(\dfrac{3}{50}=\dfrac{3\times9}{50\times9}=\dfrac{27}{450}\)

\(\dfrac{2}{9}=\dfrac{2\times50}{9\times50}=\dfrac{100}{450}\)
