Question

Решит уравнение 1/6 / 1/4х-1/3 - 3/8 =1/40

Answer 1

$frac{1}{6} : frac{1}{4} x- frac{1}{3} - frac{3}{8} = frac{1}{40}$
$frac{1}{6} * 4 x- frac{8}{24} - frac{9}{24} = frac{1}{40}$
$frac{2}{3} x- frac{17}{24} = frac{1}{40}$
$frac{2}{3} x = frac{1}{40} + frac{17}{24}$
$frac{2}{3} x = frac{3}{120} + frac{85}{120}$
$frac{2}{3} x = frac{88}{120}$
$frac{2}{3} x = frac{11}{15}$
$x = frac{11}{15} : frac{2}{3}$
$x = frac{11}{15}*frac{3}{2}$
$x = frac{11}{10}$
$x=1,1$
