Question

Ramon has a large collection of marbles.He has 150 clear marbles, 214 blue marbles, and 89 green marbles. Ramon wrote this equation about his marbles

150 + 214 + 89 = 224 + 89 + 150
What property did Roman use?

Answer 1

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.

Answer 2

Ramon used the property of equality in this equation.

Explanation:

The property of equality states that if two expressions are equal, then you can perform the same operations on both sides of the equation and the two expressions will remain equal. In this case, Ramon rearranged the terms on both sides of the equation to group the clear and green marbles together and the blue marbles separately. This is allowed because he is using the property of equality, which allows him to perform the same operations on both sides of the equation.
