[tex]1)1 \frac{2}{8} - \frac{1}{4} \\ = \frac{10}{8} - \frac{1}{4} \\ = \frac{10}{8} - \frac{2}{8} \\ = \frac{8}{8} \\ = 1[/tex]
[tex]2)2 \frac{7}{10} - 1 \frac{5}{3} \\ = \frac{27}{10} - \frac{8}{3} \\ \frac{81}{30} - \frac{80}{30} \\ = \frac{1}{30} [/tex]
[tex]3)2 \frac{1}{2} - \frac{4}{6} \\ = \frac{5}{2} - \frac{4}{6} \\ = \frac{15}{6} - \frac{4}{6} \\ = \frac{11}{6} \\ = 1 \frac{5}{6} [/tex]
[tex]4)4 \frac{7}{8} - \frac{1}{8} \\ = \frac{39}{8} - \frac{1}{8} \\ = \frac{38}{8} \\ = 4 \frac{6}{8} [/tex]
[tex]5)5 \frac{2}{4} - \frac{5}{8} \\ = \frac{22}{4} - \frac{5}{8} \\ = \frac{44}{8} - \frac{5}{8} \\ = \frac{39}{8} \\ = 4 \frac{7}{8} [/tex]
[tex]6)6 \frac{4}{6} - \frac{3}{4} \\ = \frac{40}{6} - \frac{3}{4} \\ = \frac{80}{12} - \frac{9}{12} \\ = \frac{71}{12} \\ = 5 \frac{11}{12} [/tex]
[tex]7)3 \frac{3}{4} - 1 \frac{6}{8} \\ = \frac{15}{4} - \frac{14}{8} \\ = \frac{30}{8} - \frac{14}{8} \\ = \frac{16}{8} \\ = 2 [/tex]
[tex]8)3 \frac{4}{6} - 2 \frac{7}{12} \\ = \frac{22}{6} - \frac{31}{12} \\ = \frac{44}{12} - \frac{31}{12} \\ = \frac{13}{12} \\ = 1 \frac{1}{12} [/tex]
[tex]9)6 \frac{2}{3} - 3 \frac{2}{4} \\ = \frac{20}{3} - \frac{14}{4} \\ = \frac{80}{12} - \frac{42}{12} \\ = \frac{38}{12} \\ = 3 \frac{2}{12} [/tex]
[tex]10)6 \frac{2}{2} - 4 \frac{1}{4} \\ = \frac{14}{2} - \frac{17}{4} \\ = \frac{28}{4} - \frac{17}{4} \\ = \frac{11}{4} \\ = 2 \frac{3}{4} [/tex]
