Answer:
Step-by-step explanation:
The complete question in English is attached.
The equation is:
![(1)/(2)+(2)/(5)\bigg((5)/(2)\bigg)=(1)/(2)+(5)/(2)\bigg((2)/(5)\bigg)](https://img.qammunity.org/2021/formulas/mathematics/high-school/h3xm8n7chfofzk8rao5tzvr4jrrlc818d0.png)
The commutative property of the multiplication states that the order of the factors do not change the product.
Thus, the product a · b is equal to the product b · a.
In the given equation the order of the factors 2/5 and 5/2 was changed: in the left-hand side it appears 2/5 · (5/2). On the right-hand side it appears as 5/2 · (2/5).
Thus, the equality shows the commutative property of the multiplication of rational numbers.
