Question

(1целая 1/3 + 2 целых 5/6) : (0,75 - 1 целая 1/6 ) - 15,6

Answer 1

1) 1 1/3 + 2 5/6 = 1 2/6 + 2 5/6 = 3 7/6 = 4 1/6
2) 0,75 - 1 1/6 = 3/4 - 1 1/6 = 9/12 - 1 2/12 = 9/12 - 14/12 = - 5/12
3) 4 1/6 : ( - 5/12 ) = 25/6 : ( - 5/12 ) = - 10
25
4) - 10 - 15,6 = - 25,6
Ответ ( - 25,6 )

Answer 2

$frac{1frac{1}{3}+2frac{5}{6}}{0,75-1frac{1}{6}}-15,6=frac{frac{8}{6}+frac{17}{6}}{frac{9}{12}-frac{14}{12}}-15,6=frac{25}{6}*(-frac{12}{5})-15,6=\-frac{5}{1}*frac{2}{1}-15,6=-10-15,6=-25,6=-(5^2+sqrt{0,36})$
