$$14 - \frac{6}{9} = 13\frac{9}{9} - \frac{6}{9} = 13\frac{3}{9} = 13\frac{1}{3}$$
$$82 - \frac{7}{15} = 81\frac{15}{15} - \frac{7}{15} = 81\frac{8}{15}$$
$$5 - 4\frac{3}{4} = 4\frac{4}{4} - 4\frac{3}{4} = \frac{1}{4}$$
$$44 -$$
Ответ: а) $$13\frac{1}{3}$$; б) $$81\frac{8}{15}$$; в) $$\frac{1}{4}$$
