1350/256000=50/x

Turn both sides upside down and the equation is still balanced

$$$\frac{x}{50}=\frac{256000}{1350}$$ $

Multiply both sides by 50

$$$x=\frac{50*256000}{1350}$$ $

$${\mathtt{x}} = {\frac{{\mathtt{50}}{\mathtt{\,\times\,}}{\mathtt{256\,000}}}{{\mathtt{1\,350}}}} \Rightarrow {\mathtt{x}} = {\mathtt{9\,481.481\: \!481\: \!481\: \!481\: \!481\: \!5}}$$

 This can also be written as

  $$$x = 9481\frac{13}{27}$$ $
