Answer 1

№584

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

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.
