помогите пожалуйста срочно найти

Answer 1

3)
$\frac{4}{5} - 0.9 = 0.8 - 0.9 = - 0.1 \\ - 0.1 - 0.225 = - 0.325$
$- \frac{325}{1000} \times \frac{8}{13} = - \frac{25}{125} = - \frac{1}{5} = - 0.2$
$\frac{2}{5} \div 8 = \frac{2}{5} \times \frac{1}{8} = \frac{1}{20} = 0.05$
$- 0.2 \div 0.05 = - 20 \div 5 = - 4$
Ответ:-4
4)
$\frac{4}{5} \div \frac{8}{3} = \frac{4}{5} \times \frac{3}{8} = \frac{3}{10} = 0.3$

$3 \div \frac{3}{4} = 3 \times \frac{4}{3} = 4$
$0.3 - 4 = - 3.7$
$\frac{1}{6} - \frac{1}{15} = \frac{5}{30} - \frac{2}{30} = \frac{3}{30} = 0.1$
$- 3.7 \div 0.1 = - 37$
