№2. Выполни действия:

1) \(\frac{5}{36} + \frac{13}{36} - \frac{17}{36} = \frac{5 + 13 - 17}{36} = \frac{18 - 17}{36} = \frac{1}{36}\)

2) \(4\frac{9}{32} - 1\frac{6}{32} + \frac{7}{32} = (4 - 1) + (\frac{9}{32} - \frac{6}{32} + \frac{7}{32}) = 3 + \frac{9 - 6 + 7}{32} = 3 + \frac{10}{32} = 3\frac{10}{32} = 3\frac{5}{16}\)

3) \(1 - \frac{24}{53} = \frac{53}{53} - \frac{24}{53} = \frac{53 - 24}{53} = \frac{29}{53}\)

4) \(12\frac{7}{19} - 7\frac{4}{19} = (12 - 7) + (\frac{7}{19} - \frac{4}{19}) = 5 + \frac{7 - 4}{19} = 5 + \frac{3}{19} = 5\frac{3}{19}\)

5) \(\frac{9}{18} \cdot \frac{36}{81} = \frac{1}{2} \cdot \frac{4}{9} = \frac{1 \cdot 4}{2 \cdot 9} = \frac{4}{18} = \frac{2}{9}\)

6) \(\frac{18}{35} : \frac{6}{25} = \frac{18}{35} \cdot \frac{25}{6} = \frac{3}{7} \cdot \frac{5}{1} = \frac{3 \cdot 5}{7 \cdot 1} = \frac{15}{7} = 2\frac{1}{7}\)

Ответ: 1) \(\frac{1}{36}\); 2) \(3\frac{5}{16}\); 3) \(\frac{29}{53}\); 4) \(5\frac{3}{19}\); 5) \(\frac{2}{9}\); 6) \(2\frac{1}{7}\)
