Решите задачу:

$1 \frac{4}{9}- \frac{8}{9}= \frac{13-8}{9}= \frac{5}{9} \\ \\ 5 \frac{1}{12}- \frac{3}{12}= 4 \frac{13}{12}- \frac{3}{12}=4 \frac{10}{12}=4 \frac{5}{6} \\ \\ 10 \frac{1}{8}- 4\frac{3}{8}= 5\frac{9}{8}- \frac{3}{8} = 5\frac{6}{8}=5 \frac{3}{4} \\ \\ 1 \frac{1}{7}- \frac{3}{7}= \frac{8-3}{7}= \frac{5}{7} \\ \\ 3 \frac{4}{9}- \frac{7}{9}= 2\frac{13}{9}- \frac{7}{9} = 2\frac{6}{9}=2 \frac{2}{3} \\ \\ 7 \frac{2}{19}- \frac{7}{19}=6 \frac{21}{19}- \frac{7}{19} =6 \frac{14}{19}$

$1 \frac{3}{5}- \frac{4}{5}= \frac{8-4}{5}= \frac{4}{5} \\ \\ 6 \frac{1}{5}-2 \frac{3}{5}=3 \frac{6}{5}- \frac{3}{5}=3 \frac{3}{5} \\ \\ 14 \frac{7}{21}-3 \frac{8}{21}=10 \frac{28}{21}- \frac{8}{21}=10 \frac{20}{21}$
