$5 \frac{1}{2} + \frac{2}{4} = \frac{11}{2} + \frac{2}{4} = \frac{11}{2} + \frac{1}{2} = \frac{11 + 1}{2} = \frac{12}{2} = 6$

$- 3 \frac{1}{4} - 2 \frac{1}{5} = - (3 \frac{1}{5} + 2 \frac{1}{5} ) = - ((3 + 2) + ( \frac{1}{4} + \frac{1}{5} )) = - (5 + \frac{2}{20} ) = - 5 \frac{9}{20}$

$2 \frac{1}{2} + 2 \frac{1}{3} 1 = 2 + \frac{1}{2} + 2 \frac{1}{3} - 1 = (2 + 2 - 1) + ( \frac{1}{2} + \frac{1}{3} ) = 3 \frac{5}{6}$
