Question

решите пример

(2 5/6 - 6 5/6 : 1 5/36) × 4/19=?​

Answer 1

Ответ:

$(2 \frac{5}{6} - 6 \frac{5}{6} \div 1 \frac{5}{36} ) \times \frac{4}{19} = (2 \frac{5}{6} - \frac{41}{6} \times \frac{36}{41} ) \times \frac{4}{19} = (2 \frac{5}{6} - 6 ) \times \frac{4}{19} = ( \frac{17}{6} - \frac{36}{6} ) \times \frac{4}{19} = ( \frac{17 - 36}{6} ) \times \frac{4}{19} = - \frac{19}{6} \times \frac{4}{19} = - \frac{4}{6} = - \frac{2}{3}$
