Answer 1

1.

$6 \frac{5}{8} + \frac{2}{8} = 6 \frac{7}{8}$

$4 + 2 \frac{2}{3} = 6 \frac{2}{3}$

$4 \frac{3}{8} + 2 \frac{5}{8} = 6 \frac{8}{8} = 7$

$2 \frac{2}{9} + 3 \frac{5}{9} = 5 \frac{7}{9}$

$3 \frac{5}{7} + 8 = 11 \frac{5}{7}$

$2 \frac{7}{13} + 3 \frac{8}{13} = 5 \frac{15}{13} = 6 \frac{2}{13}$

2.

$4 \frac{14}{19} - 2 \frac{5}{19} = 2 \frac{9}{19}$

$12 - \frac{7}{18} = 11 \frac{18}{18} - \frac{7}{18} = 11 \frac{11}{18}$

$8 \frac{7}{15} - 3 \frac{11}{15} = 4 \frac{11}{15}$

$8 \frac{7}{10} - 5 = 3 \frac{7}{10}$

$11 - 3 \frac{5}{12} =10 \frac{12}{12} - 3 \frac{5}{12} = 7 \frac{7}{12}$

$10 \frac{9}{14} - 3 \frac{9}{14} = 7$
