Answer 1

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

\(MSC:25\\ \dfrac{3}{5}=\dfrac{3\times5}{5\times5}=\dfrac{15}{25}\\ \dfrac{4}{25}< \dfrac{15}{25}\\ \Rightarrow\dfrac{4}{25}< \dfrac{3}{5}\)         

 

Answer 2

\(\dfrac{5}{8}=\dfrac{5.3}{8.3}=\dfrac{15}{24}>\dfrac{14}{24}\)

=>\(\dfrac{5}{8}>\dfrac{14}{24}\)

\(\dfrac{3}{5}=\dfrac{3.5}{5.5}=\dfrac{15}{24}>\dfrac{4}{25}\)

=>\(\dfrac{4}{25}< \dfrac{3}{5}\)
