Question

Решите пожалуйста
2 3/5:(х+1 3/14)-1 2/5=1/3

Answer 1

$2frac{3}{5}:(x+1frac{3}{14})-1frac{2}{5}=frac{1}{3}$

$frac{13}{5}:(x+frac{17}{14})=frac{1}{3}+frac{7}{5}$

$frac{13}{5}:(x+frac{17}{14})=frac{5+21}{15}$ 

$frac{13}{5}:(x+frac{17}{14})=frac{26}{15}$ 

$(x+frac{17}{14})=frac{13}{5}:frac{26}{15}$

$(x+frac{17}{14})=frac{13}{5}*frac{15}{26}$ 

$x+frac{17}{14}=frac{3}{2}$

$x=frac{3}{2}-frac{17}{14}$

$x=frac{21-17}{14}$

$x=frac{4}{14}$ 

$x=frac{2}{7}$
