By cross multiplying we can write given expression as

<h3>Commutative property: commutative property states that order does not matter.</h3><h3> In addition , commutative property</h3>
a+b=b+a
<h3>In multiplication , commutative property </h3>

We can write commutative property in multiplication
ab=ba
Therefore, by using commutative property then we get
