Вариант 4. Выполните вычитание:
- \( 1 - \frac{5}{6} = \frac{6}{6} - \frac{5}{6} = \frac{1}{6} \)
- \( 5 \frac{2}{5} - 1 \frac{3}{5} = 4 \frac{7}{5} - 1 \frac{3}{5} = 3 \frac{4}{5} \)
- \( 2 \frac{13}{14} - 1 \frac{20}{21} = 2 \frac{39}{42} - 1 \frac{40}{42} = 1 \frac{81}{42} - 1 \frac{40}{42} = 1 \frac{41}{42} \)
- \( 8 \frac{3}{4} - 7 \frac{5}{6} = 8 \frac{9}{12} - 7 \frac{10}{12} = 7 \frac{21}{12} - 7 \frac{10}{12} = \frac{11}{12} \)
- \( 2 \frac{5}{8} - 1 \frac{3}{10} = 2 \frac{25}{40} - 1 \frac{12}{40} = 1 \frac{13}{40} \)
- \( 8 \frac{19}{20} - 3 \frac{7}{30} = 8 \frac{57}{60} - 3 \frac{14}{60} = 5 \frac{43}{60} \)
Ответ: а) 1/6; б) 3 4/5; в) 1 41/42; г) 11/12; д) 1 13/40; е) 5 43/60.
