Срочно!!! Кто решит–40 балов
х+2 1/3+3 1/9-1 1/12=5 7/12

Answer 1

$x+2 frac{1}{3} +3 frac{1}{9} -1 frac{1}{12} =5 frac{7}{12} ;$
$x+ frac{7}{3} +frac{28}{9} - frac{13}{12} =frac{67}{12} ;$
$x+ frac{21}{9} +frac{28}{9}=frac{67}{12}+frac{13}{12};$
$x+ frac{49}{9}=frac{80}{12};$
$x=frac{80}{12}- frac{49}{9} = frac{240-196}{36} = frac{44}{36} = frac{11}{9} =1 frac{2}{9}$
