Prove commutative property for rational numbers

The commutative property for rational numbers:

The commutative property for addition or multiplication states that we can add or multiply rational numbers in any order.

$a + b = b + a$

For example,

$\frac{2}{5} + \frac{1}{5} =\frac{2+1}{5} = \frac{3}{5}$

$\frac{1}{5} + \frac{2}{5} = \frac{1+2}{5} = \frac{3}{5}$.
