$\dfrac{36}{54}=\dfrac{36:18}{54:18}=\dfrac{2}{3}\\\\\dfrac{47}{n}=\dfrac{2}{3}\ \ \ |cross\ multiply\\\\2\cdot n=3\cdot47\\\\2n=141\ \ \ \ |divide\ both\ sides\ by\ 2\\\\n=\dfrac{141}{2}\\\\\boxed{n=70.5}$

Answer 2

$47/n = 36/54$ 

$47/n=2/3$ 

$47=2/3n$ 

$47=2n/3$ 

$47*3=2n$ 

$141=2n$

$141/2=n$
