Вычислите: 1/4+7/12+1 целая 1/3 - (1 целая1/6 - 1/2)Срочно

Решите задачу:

$\frac{1}{4} + \frac{7}{12} +1 \frac{1}{3} - (1 \frac{1}{6} - \frac{1}{2} )= 1 \frac{1}{2} \\\\\\\\\ \textgreater \ 1 \frac{1}{6} - \frac{1}{2} = \frac{7}{6} - \frac{1}{2} = \frac{7}{6} - \frac{3}{6} = \frac{4}{6} = \frac{2}{3} \\\\\ \textgreater \ \frac{1}{4} + \frac{7}{12} = \frac{3}{12} + \frac{7}{12}= \frac{10}{12}= \frac{5}{6}\\\\\ \textgreater \ \frac{5}{6}+1 \frac{1}{3} - \frac{2}{3} = \frac{5}{6}+ \frac{4}{3} - \frac{2}{3}=\frac{5}{6} + \frac{2}{3}=\frac{5}{6}+\frac{4}{6}=\frac{9}{6}=\frac{3}{2}=1 \frac{1}{2}$
