1. [tex]1\frac{1}{2} + \frac{5}{8} = 1\frac{4}{8} + \frac{5}{8} = 1\frac{9}{8} = 2\frac{1}{8}[/tex]
2. [tex]1\frac{1}{3} + 2\frac{4}{5} = 1\frac{5}{15} + 2\frac{12}{15} = 3\frac{17}{15} = 4\frac{2}{15}[/tex]
3. [tex]4\frac{2}{3} + 1\frac{3}{8} = 4\frac{16}{24} + 1\frac{9}{24} = 5\frac{25}{24} = 6\frac{1}{24}[/tex]
4. [tex]6\frac{5}{7} + 3\frac{2}{3} = 6\frac{15}{21} + 3\frac{14}{21} = 9\frac{29}{21} = 10\frac{8}{21}[/tex]
5. [tex]5\frac{4}{5} +2\frac{6}{7} = 5\frac{28}{35} + 2\frac{30}{35} = 7\frac{58}{35} = 8\frac{23}{35}[/tex]
6. [tex]6\frac{5}{8} + 1\frac{3}{5} = 6\frac{25}{40} + 1\frac{24}{40} = 7\frac{49}{40} = 8\frac{9}{40}[/tex]
7. [tex]7\frac{7}{8} + 1\frac{5}{6} = 7\frac{21}{24} + 1\frac{20}{24} = 8\frac{41}{24} = 9\frac{17}{24}[/tex]
8. [tex]10\frac{5}{7} + 3\frac{7}{9} = 10\frac{45}{63} + 3\frac{49}{63} = 13\frac{94}{63} = 14\frac{31}{63}[/tex]
