so sánh 5/8va 14/24
\(MSC:24\\ \dfrac{5}{8}=\dfrac{5\times3}{8\times3}=\dfrac{15}{24}\\ \dfrac{15}{24}>\dfrac{14}{24}\\ \Rightarrow\dfrac{5}{8}>\dfrac{14}{24}\)
4/25va 3/5
\(MSC:25\\ \dfrac{3}{5}=\dfrac{3\times5}{5\times5}=\dfrac{15}{25}\\ \dfrac{4}{25}< \dfrac{15}{25}\\ \Rightarrow\dfrac{4}{25}< \dfrac{3}{5}\)
\(\dfrac{5}{8}=\dfrac{5.3}{8.3}=\dfrac{15}{24}>\dfrac{14}{24}\)
=>\(\dfrac{5}{8}>\dfrac{14}{24}\)
\(\dfrac{3}{5}=\dfrac{3.5}{5.5}=\dfrac{15}{24}>\dfrac{4}{25}\)
=>\(\dfrac{4}{25}< \dfrac{3}{5}\)
