ПОМОГИТЕ УМОЛЯЮ!!!!!!!!!! Вычислите [latex] (3\frac{1}{12}- 2\frac{3}{4}):(1 \frac{1}{6}- \frac{5}{12}). [/latex] С РЕШЕНИЕ УМОЛЯЮ!!!!!!!!!!!!!!!!!!

По действиям: [latex]3 \frac{1}{12} -2 \frac{3}{4} =3 \frac{1}{12} -2 \frac{9}{12}=2 \frac{13}{12} -2 \frac{9}{12}= \frac{4}{12} \\ \\ 1 \frac{1}{6} - \frac{5}{12}= \frac{7}{6} - \frac{5}{12}= \frac{14}{12} - \frac{5}{12}= \frac{9}{12} \\ \\ \frac{4}{12} :\frac{9}{12}=\frac{4}{12} *\frac{12}{9}= \frac{4}{9} [/latex]
