Вариант 2. a) 1-4 9 Выполните вычитание: б)4-3- 4 3 г) 7-3- 10 1 6 4 9 д) 5-4- 21 14 11 e) 5- 33 22

a) $$1 - \frac{4}{9} = \frac{9}{9} - \frac{4}{9} = \frac{5}{9}$$

б) $$4\frac{4}{9} - 3\frac{3}{4} = 4\frac{16}{36} - 3\frac{27}{36} = 3\frac{52}{36} - 3\frac{27}{36} = \frac{25}{36}$$

г) $$7\frac{10}{10} - 3\frac{1}{6} = 7\frac{3}{3} - 3\frac{1}{6} = 6\frac{6}{6} - 3\frac{1}{6} = 3\frac{5}{6}$$

д) $$5\frac{4}{21} - 4\frac{11}{14} = 5\frac{8}{42} - 4\frac{33}{42} = 4\frac{50}{42} - 4\frac{33}{42} = \frac{17}{42}$$

е) $$5\frac{5}{33} - \frac{4}{22} = 5\frac{10}{66} - \frac{12}{66} = 4\frac{76}{66} - \frac{12}{66} = 4\frac{64}{66} = 4\frac{32}{33}$$

Ответ: a) $$\frac{5}{9}$$; б) $$\frac{25}{36}$$; г) $$3\frac{5}{6}$$; д) $$\frac{17}{42}$$; е) $$4\frac{32}{33}$$
