Question

(2,4:(-0,6-3 1/2:1 3/4)*3,2

Answer 1

$(2.4 div ( - 0.6 - 3 frac{1}{2} div 1 frac{3}{4} )) times 3.2 =?$

1)
$- 3 frac{1}{2} div 1 frac{3}{4} = - frac{7}{2} times frac{4}{7} = - 2$

2)
$- 0.6 - 2 = - 2.6$

3)
$2.4 div ( - 2.6) = 2 frac{4}{10} div ( - 2 frac{6}{10} ) = frac{24}{10} times ( - frac{10}{26} ) = - frac{12}{13}$

4)
$- frac{12}{13} times 3.2 = - frac{12}{13} times frac{32}{10} = - frac{6}{13} times frac{32}{5} = - frac{192}{65} = - 2 frac{62}{65} = - 2.954$

Ответ: $- 2 frac{62}{65}$или$- 2.954$
