Answer: It looks like Ramon used the property of addition known as the Commutative Property in this equation.
Step-by-step explanation: The Commutative Property states that the order in which numbers are added does not change the sum. In other words, it doesn't matter whether you add the numbers first, second, or third – the result will always be the same.
So, in this equation, Ramon is saying that the total number of clear marbles plus the total number of blue marbles plus the total number of green marbles is equal to the total number of green marbles plus the total number of blue marbles plus the total number of clear marbles.
Using this property, Ramon was able to simplify his equation and show that the total number of marbles in his collection is the same regardless of the order in which they are counted.
