\(\frac{18}{91}< \frac{18}{90}=\frac{1}{5}\)
\(\frac{23}{114}>\frac{23}{115}=\frac{1}{5}\)
=> \(\frac{18}{91}< \frac{23}{114}\)
\(\frac{21}{52}=\frac{210}{520}=1-\frac{310}{520}\)
\(\frac{213}{523}=1-\frac{310}{523}\)
Vì \(\frac{310}{520}>\frac{310}{523}\)=> \(1-\frac{310}{520}< 1-\frac{310}{523}\)
=> \(\frac{21}{52}< \frac{213}{523}\)
\(\frac{18}{91}< \frac{18}{90}=\frac{1}{5}=\frac{23}{115}< \frac{23}{114}\)
\(=>\frac{18}{91}< \frac{23}{114}\)
