3. Выполните действия: 1) 0,56 : \(\frac{3}{8}\); 2) 2\(\frac{1}{9}\) \(\cdot \) 1,8; 3) 2,448 : \(\frac{8}{9}\); 4) 8,4 : 1\(\frac{1}{6}\).

1) 0,56 : \(\frac{3}{8}\) = \(\frac{56}{100} \cdot \frac{8}{3}\) = \(\frac{14}{25} \cdot \frac{8}{3}\) = \(\frac{112}{75}\) = 1\(\frac{37}{75}\)

Ответ: 1\(\frac{37}{75}\)

2) 2\(\frac{1}{9}\) \(\cdot \) 1,8 = \(\frac{19}{9} \cdot \frac{18}{10}\) = \(\frac{19}{1} \cdot \frac{2}{10}\) = \(\frac{38}{10}\) = 3,8

Ответ: 3,8

3) 2,448 : \(\frac{8}{9}\) = \(\frac{2448}{1000} \cdot \frac{9}{8}\) = \(\frac{306}{125} \cdot \frac{9}{1}\) = \(\frac{2754}{125}\) = 22,032

Ответ: 22,032

4) 8,4 : 1\(\frac{1}{6}\) = \(\frac{84}{10} : \frac{7}{6}\) = \(\frac{42}{5} \cdot \frac{6}{7}\) = \(\frac{6}{5} \cdot \frac{6}{1}\) = \(\frac{36}{5}\) = 7,2

Ответ: 7,2
