По действиям

Answer 1

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

Answer 2

1) 6/25 - 1/5 = (6 - 5) / 25 = 1/25

2) 10 : 1/5 = 10 * 25 = 250

3) 250 * 5/6 = 125 * 5/3 = 625/3 = 208 1/3

4) 208 1/3 - 27 = (625/3)-27 = 544/3 = 181 1/3
