Vì 2016>2013.
=>\(\frac{387}{2016}< \frac{387}{2013}\left(1\right)\)
Vì 387>109.
=>\(\frac{387}{2016}>\frac{109}{2016}\left(2\right)\)
Từ (1) và (2),suy ra:
\(\frac{109}{2016}< \frac{387}{2013}\)
Vậy............
\(\frac{109}{2016}\)và \(\frac{387}{2013}\)
\(\frac{109}{2016}=\frac{109}{2016}+\frac{1907}{2016}\) \(\frac{387}{2013}=\frac{387}{2013}+\frac{1626}{2013}\)
Ta thấy \(\frac{1907}{2016}>\frac{1626}{2013}\)
\(\Rightarrow\frac{109}{2016}>\frac{387}{2013}\)
\(\frac{109}{2016}< \frac{327}{2016}< \frac{327}{2013}< \frac{387}{2013}\)
Vậy \(\frac{109}{2016}< \frac{387}{2013}\)
