a) $$14 - \frac{6}{9} = 13 + 1 - \frac{6}{9} = 13 + \frac{9}{9} - \frac{6}{9} = 13 + \frac{3}{9} = 13 \frac{3}{9} = 13 \frac{1}{3}$$

б) $$82 - \frac{7}{15} = 81 + 1 - \frac{7}{15} = 81 + \frac{15}{15} - \frac{7}{15} = 81 + \frac{8}{15} = 81 \frac{8}{15}$$
Ответ: 81 8/15
в) $$5 - 4 \frac{3}{4} = 4 + 1 - 4 - \frac{3}{4} = 4 + \frac{4}{4} - 4 - \frac{3}{4} = 1 - \frac{3}{4} = \frac{1}{4}$$
Ответ: 1/4
г) $$44 - 3 \frac{8}{11} = 43 + 1 - 3 - \frac{8}{11} = 43 + \frac{11}{11} - 3 - \frac{8}{11} = 40 + \frac{3}{11} = 40 \frac{3}{11}$$
