$3\frac{1}{4} + 5\frac{2}{8}\\3\frac{2}{8} + 5\frac{2}{8}\\\\=8\frac{4}{8}\\ =8 \frac{1}{2}$

$3\frac{1}{9} - 1\frac{2}{3} \\3\frac{1}{9} - 1\frac{6}{9}\\2\frac{10}{9} -1\frac{6}{9}\\\1\frac{4}{9}$

$4\frac{1}{2} -2\frac{3}{5}\\ 4\frac{5}{10} - 2 \frac{6}{10}\\ 3\frac{15}{10}- 2 \frac{6}{10}\\\\= 1\frac{9}{10}$
