Номер 242 Помогите плиз

Answer 1

1) $12: 1frac{1}{5} =12: frac{5*1+1}{5} =12: frac{6}{5} =12* frac{5}{6} = frac{12*5}{6} = frac{2*6*5}{6} = frac{10}{1}$
2)0,8:1,6=$frac{8}{10}: frac{16}{10}= frac{8}{10} frac{10}{16}= frac{8*10}{10*8*2}= frac{1}{2}$
3) $2frac{1}{6}: 4 frac{1}{3}= frac{2*6+1}{6}: frac{4*3+1}{3}= frac{13}{6}:frac{13}{3} = frac{13}{2*3}* frac{3}{13} = frac{1}{2}$
4)5,6:14=$frac{56}{10} :14= frac{2*2*14}{2*5*14} = frac{2}{5}$
5) $frac{4}{15} :frac{2}{3}= frac{2*2}{3*5}* frac{3}{2} = frac{2}{5}$
6)12,3:1,23=$frac{123}{10}: frac{123}{100} = frac{123}{10}* frac{10*10}{123} = frac{10}{1}$
