[tex]10 \frac{3}{5} +1 \frac{1}{5} = 11 \frac{4}{5} [/tex]
[tex]23 \frac{2}{3} + 15 \frac{1}{3} = 38 \frac{3}{3} = 39[/tex]
[tex]39 \frac{1}{2} + 1 \frac{2}{3} = 40 \frac{3 +4 }{6} = 40 \frac{7}{6} = 41 \frac{1}{6} [/tex]
[tex]1 \frac{1}{2} + 1 \frac{1}{2} = 2 \frac{2}{2} = 3[/tex]
[tex]8 \frac{5}{6} - 2 \frac{3}{6} = 6 \frac{5 - 3}{6} = 6 \frac{2}{6} = 6 \frac{1}{3} [/tex]
