Question

Помогите, тут нужен распределительный закон

Answer 1

Вроде бы так : -11,1/4*(1,11/27-2,16/27)

Answer 2

$- 11 frac{1}{4} (1 frac{11}{27} - 2 frac{16}{27} ) = - 45 \ - 11 frac{1}{4} times 1 frac{11}{27} = - frac{45}{4} times frac{38}{27} =$
$= - frac{5 times 19}{2 times 3} = - frac{95}{6} = - 15 frac{5}{6}$
$- frac{45}{4} times frac{70}{27} = - frac{5 times 35}{2 times 3} = - frac{175}{6} \ = - 29 frac{1}{6}$
$- 15 frac{5}{6} - 29 frac{1}{6} = - 44 frac{6}{6} = - 45$
