ta có \(\frac{15}{301}=\frac{15.499}{301.499}=\frac{7485}{150199}\)
\(\frac{25}{499}=\frac{25.301}{499.301}=\frac{7525}{150199}\)
mà \(\frac{7485}{150199}< \frac{7525}{150199}\)
⇒ \(\frac{15}{301}< \frac{25}{499}\)
\(\frac{15}{301}< \frac{15}{300}=\frac{1}{20}\)
\(\frac{25}{499}>\frac{25}{500}=\frac{1}{20}\)
\(\Rightarrow\frac{25}{499}>\frac{15}{301}\)
