[tex]2 \frac{3}{3} + 1 \frac{3}{5} = 3 + 1 \frac{3}{5} = 4 \frac{3}{5} [/tex]
[tex]3 \frac{1}{6} - 1 \frac{4}{9} = 3 \frac{3}{18} - 1 \frac{8}{18} = 2 \frac{21}{18} - 1 \frac{8}{18} = 1 \frac{13}{18} [/tex]
[tex]3 \frac{1}{5} - 2 \frac{4}{5} + 1 \frac{3}{5} = 2 \frac{6}{5} - 2 \frac{4}{5} + 1 \frac{3}{5} = \frac{2}{5} + 1 \frac{3}{5} = 1 \frac{5}{5} = 2[/tex]
