Answer 1

Ответ:

$1) \frac{4}{5} \times \frac{15}{16} = \frac{3}{4} \\ 2) \frac{10}{13} \times \frac{39}{40} = \frac{3}{4} \\ 3) \frac{5}{12} \times \frac{6}{25} = \frac{1}{10} \\ 4) \frac{11}{12} \times \frac{4}{33} = \frac{1}{9} \\ 5) \frac{4}{15} \times \frac{25}{28} = \frac{5}{21} \\ 6) \frac{35}{36} \times \frac{54}{55} = \frac{21}{22} \\ 7) \frac{9}{14} \times \frac{49}{63} = \frac{1}{2} \\ 8) \frac{22}{35} \times \frac{63}{121} = \frac{18}{55}$
