Question

помогите сделать номер 60

Answer 1

$frac{5}{6}*frac{3}{20}= frac{1}{2}*frac{1}{4}= frac{1}{8} = 0,125$

$frac{3}{7}*frac{6}{11} = frac{18}{77}$

$frac{10}{11}*frac{11}{26}=frac{5}{1}*frac{1}{13}= frac{5}{13}$

$frac{19}{42}*frac{21}{38}= frac{1}{2}*frac{1}{2}= frac{1}{4} = 0,25$

$frac{24}{65}*frac{39}{40}= frac{3}{5}*frac{3}{5} = frac{9}{25}=0,36$

$frac{25}{36}*frac{51}{70}= frac{5}{12}*frac{17}{14}=frac{85}{168}$
