$x=214.25$

$73%$ means $73/100$

Let $73%$ of $x$ be $156.4$

This means $73/100$ of $x$ is $156.4$ and in equation form, we can write it as

$73/100 xx x=156.4=1564/10$

or $73/100 xx 100/73 xx x=1564/10xx100/73$

or $x=1564/10xx100/73$

As $73$ is a prime number and $1564$ is not a multiple of $73$ ,

we have to use a calculator and using it to calculate (up to 2dp)

$x=214.25$
