1) $(\frac{3}{4} + \frac{1}{20}) * \frac{1}{2} = \frac{15}{20} + \frac{1}{20} = \frac{16}{20} * \frac{1}{2} = \frac{8}{20} = \frac{2}{5} = 0,4$

НОЗ: 20.

2) $(\frac{7}{12} - \frac{1}{3}) * \frac{16}{19} = \frac{7}{12} - \frac{4}{12} = \frac{3}{12} * \frac{16}{19} = \frac{12}{57} = \frac{4}{19}$

НОЗ: 12.

3) $(\frac{38}{5} - \frac{34}{15}) * \frac{9}{32} = \frac{114}{15} - \frac{34}{15} = \frac{80}{15} * \frac{9}{32} = \frac{45}{30} = 1\frac{15}{30} = 1,5$

НОЗ: 15.

4) $(\frac{11}{24} + \frac{1}{6}) * \frac{8}{5} = \frac{11}{24} + \frac{4}{24} = \frac{15}{24} * \frac{8}{5} = \frac{3}{3} = 1$

НОЗ: 24.

5) $(\frac{11}{2} + \frac{13}{5}) * \frac{5}{9} = \frac{55}{10} + \frac{26}{10} = \frac{81}{10} * \frac{5}{9} = \frac{9}{2} = 4,5$

НОЗ: 10.

6) $(\frac{7}{1} - \frac{37}{16}) * \frac{4}{25} = \frac{112}{16} - \frac{37}{16} = \frac{75}{16} * \frac{4}{25} = \frac{3}{4} = 0,75$

НОЗ: 16.
