4.1/2:1.1/2=?1.2/3:1.1/10=? 10.1/3:2.2/3=?4/15:3.1/15 Помогите плиииз

Ответ:

Пошаговое объяснение:

$4\frac{1}{2}:1\frac{1}{2}=\frac{9}{2}:\frac{3}{2}=\frac{9}{2}*\frac{2}{3}=3\\\\ 1\frac{2}{3}:1\frac{1}{10}=\frac{5}{3}:\frac{11}{10}=\frac{5}{3}*\frac{10}{11}=\frac{50}{33}=1\frac{17}{33}\\\\ 10\frac{1}{3}:2\frac{2}{3}=\frac{31}{3}:\frac{8}{3}=\frac{31}{3}*\frac{3}{8}=\frac{31}{8}= 3\frac{7}{8}\\\\\frac{4}{15}:3\frac{1}{15}=\frac{4}{15}:\frac{46}{15}=\frac{4}{15}*\frac{15}{46}=\frac{2}{23}$
