Вычислите (4/5 + 1/6) * (23 2/3 - 15 5/9) * 45/58 - 1/2

$( \frac{4}{5}+ \frac{1}{6} )*(23 \frac{2}{3}-15 \frac{5}{9})* \frac{45}{58} - \frac{1}{2} =$ $5 \frac{7}{12}$

1) $\frac{4}{5}+ \frac{1}{6} = \frac{24}{30}+ \frac{5}{30}= \frac{29}{30}$

2) $23 \frac{2}{3}-15 \frac{5}{9} =23 \frac{6}{9}-15 \frac{5}{9}=8 \frac{1}{9}$

3) $\frac{29}{30}* \frac{73}{9}* \frac{45}{58}= \frac{73}{12}=6 \frac{1}{12}$

4) $6 \frac{1}{12} - \frac{1}{2}= 6 \frac{1}{12} - \frac{6}{12}=5 \frac{7}{12}$
