Answer
$\frac{x}{5}\times\frac{1}{3}$
Work Step by Step
The commutative property of multiplication holds that $a\times b=b\times a$.
In this example, we can set $a\times b=\frac{1}{3}\times\frac{x}{5}$.
So, $a=\frac{1}{3}$ and $b=\frac{x}{5}$.
So an equivalent expression would be $b\times a=\frac{x}{5}\times\frac{1}{3}$.
