Question

Решите:
$( 2 frac{4}{7} : ( - frac{3}{14} ) - ( - 5,7 ) )$ × $( -3 frac{1}{3} )$

Answer 1

$(2 frac{4}{7} :(- frac{3}{14} )-(-5.7))*(-3 frac{1}{3} )=21 \ 1) 2 frac{4}{7} :(- frac{3}{14} )=-( frac{18*14}{7*3} )=- 6*2=-12 \ 2)-12+5.7=-6.3=-6 frac{3}{10} =- frac{63}{10} \ 3) -frac{63}{10} *(- frac{10}{3} )= frac{63*10}{10*3} =21$

Answer 2

$(2 frac{4}{7} :(- frac{3}{14} )-(-5.7))*(-3 frac{1}{3}) = 21 \ \ 1) [tex](2 frac{4}{7} :(- frac{3}{14} )-(-5.7))*(-3 frac{1}{3}) = -31 \ \ 1) 2 frac{4}{7} :(- frac{3}{14}) =- frac{18}{7} * frac{14}{3} =-6*2=-12 \ \ 2)-12-(-5.7)=-12+5.7=-6.3 \ \ 3)(-6.3)*(-3 frac{1}{3}) =-6.3*(- frac{10}{3} )= frac{63}{3} =21$
