СРОЧНО 10:(6/25-1/5)*5/6-27 По действиям

Решите задачу:

$10 \div ( \frac{6}{25} - \frac{1}{5} ) \times \frac{5}{6} - 27 = 181 \frac{1}{3} \\ \frac{6}{25} - \frac{1}{5} = \frac{6 - 1 \times 5}{25} = \frac{6 - 5}{25} = \frac{1}{25} \\ 10 \div \frac{1}{25} = \frac{10 \times 25}{1} = 250 \\ 250 \times \frac{5}{6} = \frac{250 \times 5}{6} = \frac{1250}{6} = \frac{625}{3} = 208 \frac{1}{3} \\ 208 \frac{1}{3} - 27 = 181 \frac{1}{3}$
