Answer 2

$1\frac{2}{7} : 5\frac{1}{7} = \frac{2}{3} : x$

$\frac{9}{7} : \frac{36}{7} = \frac{2}{3} : \frac{x}{1}$

$\frac{9}{7} * \frac{7}{36} = \frac{2}{3} : \frac{x}{1}$

$\frac{9}{36} = \frac{2}{3} : \frac{x}{1}$

$\frac{1}{4} = \frac{2}{3} : \frac{x}{1}$

$\frac{1}{4} * \frac{x}{1} = \frac{2}{3}$

$\frac{x}{4} = \frac{2}{3}$

$3x = 4 * 2$

$3x = 8$

$x = \frac{8}{3}$

$x = 2\frac{2}{3}$
