Question

(2-3/-4/5)*20 пж 10 даю

Answer 1

Пошаговое объяснение:

$1)2 - \frac{3}{4} = \frac{2}{1} - \frac{3}{4} = \frac{2}{4} - \frac{3}{4} = \frac{8}{4} - \frac{3}{4} = \frac{5}{4}$

$2) \frac{5}{4} - \frac{4}{5} = \frac{5}{20} - \frac{4}{20} = \frac{25}{20} - \frac{16}{20} = \frac{9}{20}$

$3) \frac{9}{20} \times 20 = \frac{9}{1} = 9$
