3 9/14 :2 1/7=x:1,5 решите пж

Решите задачу:

$3 \frac{9}{14} : 2 \frac{1}{7} =x:1,5$
$\frac{3*14+9}{14} : \frac{2*7+1}{7} =x: \frac{15}{10}$
$\frac{51}{14} : \frac{15}{7} =x: \frac{3}{2}$
$\frac{51}{14} * \frac{7}{15} =x* \frac{2}{3}$
$\frac{17}{2*5} =x* \frac{2}{3}$
$\frac{17}{10} =x* \frac{2}{3}$
$\frac{17}{10} : \frac{3}{2} =x$
$\frac{17}{10} * \frac{2}{3} =x$
$\frac{17}{5*3} =x$
$\frac{17}{15} =x$
$x = 1 \frac{2}{15}$
