11 3/7 - 5 1/3
8 3/5 - 6 3/10

11, 3/7 - 5, 1/3 = 11, 9/21 - 5, 7/21 = 6, 2/21
8, 3/5 - 6, 3/10 = 8, 6/10 - 6, 3/10 = 2, 3/10

[tex]11 \frac{3}{7} - 5 \frac{1}{3} = \frac{33}{7} - \frac{5}{3} = \frac{64}{23} = 3 \frac{1}{21} [/tex]


[tex]8 \frac{3}{5} - 6 \frac{3}{10} = \frac{24}{5} - \frac{9}{5} = 3[/tex]
