Чтобы сравнить дроби - нужно привести их к общему знаменателю :

$\frac{6}{13}$ = $\frac{6 * 2}{13 * 2}$ = $\frac{12}{26}$ , значит :
$\frac{6}{13}$ > $\frac{11}{26}$

$\frac{3}{8}$ = $\frac{3 * 5}{8 * 5}$ = $\frac{15}{40}$
$\frac{2}{5}$ = $\frac{2 * 8}{5 * 8}$ = $\frac{16}{40}$ , значит :
$\frac{3}{8}$ < $\frac{2}{5}$
