Вариант 2. Выполните вычитание: a) 1 - 4/9 б) 8 8/15 - 9/20 в) 4 3/4 - 3 1/4 г) 9 4/21 - 4 11/14 д) 7 1/10 - 3 1/6 е) 5 5/33 - 4 7/22

Вариант 2. Выполните вычитание:

1. \( 1 - \frac{4}{9} = \frac{9}{9} - \frac{4}{9} = \frac{5}{9} \)
2. \( 8 \frac{8}{15} - \frac{9}{20} = 8 \frac{32}{60} - \frac{27}{60} = 8 \frac{5}{60} = 8 \frac{1}{12} \)
3. \( 4 \frac{3}{4} - 3 \frac{1}{4} = 1 \frac{2}{4} = 1 \frac{1}{2} \)
4. \( 9 \frac{4}{21} - 4 \frac{11}{14} = 9 \frac{8}{42} - 4 \frac{33}{42} = 8 \frac{50}{42} - 4 \frac{33}{42} = 4 \frac{17}{42} \)
5. \( 7 \frac{1}{10} - 3 \frac{1}{6} = 7 \frac{3}{30} - 3 \frac{5}{30} = 6 \frac{33}{30} - 3 \frac{5}{30} = 3 \frac{28}{30} = 3 \frac{14}{15} \)
6. \( 5 \frac{5}{33} - 4 \frac{7}{22} = 5 \frac{10}{66} - 4 \frac{21}{66} = 4 \frac{76}{66} - 4 \frac{21}{66} = 4 \frac{55}{66} = 4 \frac{5}{6} \)

Ответ: а) 5/9; б) 8 1/12; в) 1 1/2; г) 4 17/42; д) 3 14/15; е) 4 5/6.
