Answer 2

$\displaystyle \frac{5}{6}+\frac{7}{12}:\frac{7}{2}=\frac{5}{6}+\frac{7}{12}*\frac{2}{7}=\\\\\\ =\frac{5}{6}+\frac{7*2}{12*7}=\frac{5}{6}+\frac{14}{84}=\frac{5}{6}+\frac{14*1}{14*6}=\\\\ \\=\frac{5}{6}+\frac{1}{6}=\frac{5+1}{6}=\frac{6}{6}=1$

по действиям:

$\displaystyle \frac{7}{12}:\frac{7}{2}=\frac{7}{12}*\frac{2}{7}=\frac{7*2}{12*7}=\frac{14}{84}=\frac{14*1}{14*6}=\frac{1}{6}$

$\displaystyle \frac{5}{6}+\frac{1}{6}=\frac{5+1}{6}=\frac{6}{6}=1$
