$x=2/3$

Given,

$x/2=5/15$

Multiply both sides by $2$ .

$color(blue)2(x/2)=color(blue)2(5/15)$

$color(red)cancelcolor(blue)(2)(x/color(red)cancelcolor(black)2)=color(blue)2(5/15)$

Simplify.

$x=10/15$

Since the numerator and denominator can be divided by a common factor of $5$ , their values are reduced.

$x=(10color(red)(-:5))/(15color(red)(-:5))$

$x=color(green)(|bar(ul(color(white)(a/a)color(black)(2/3)color(white)(a/a)|)))$
