Answer:
Explanation:
The complete question in English is attached.
The equation is:
[tex]\dfrac{1}{2}+\dfrac{2}{5}\bigg(\dfrac{5}{2}\bigg)=\dfrac{1}{2}+\dfrac{5}{2}\bigg(\dfrac{2}{5}\bigg)[/tex]
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.
