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)
$frac{4}{5} div frac{8}{3} = frac{4}{5} times frac{3}{8} = frac{3}{10} = 0.3$

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