(2)\(\displaystyle 2\frac{1}{2} , \frac{7}{2}\)
\(\displaystyle 2\frac{1}{2} < \frac{7}{2}\)
(3)\(\displaystyle \frac{21}{41} , \frac{20}{41}\)
\(\displaystyle \frac{21}{41} > \frac{20}{41}\)
(4)\(\displaystyle \frac{11}{5} , 3\frac{3}{5}\)
\(\displaystyle \frac{11}{5} < 3\frac{3}{5}\)
(5)\(\displaystyle \frac{1}{6} , \frac{5}{6}\)
