Question

4-14/33*1 1/21 розписати​

Answer 1

Ответ:

$4 - \frac{14}{33} \times 1 \frac{1}{21} = \\ 1) \frac{14}{33} \times \frac{1 \times 21 + 1}{21} = \frac{14}{33} \times \frac{22}{21} = \frac{2}{3} \times \frac{2}{3} = \frac{4}{6} = \frac{2}{3} \\ 4 - \frac{2}{3} = \frac{4 \times 3}{3} - \frac{2}{3} = \frac{10}{3} = 3 \frac{1}{3}$
