Question

Think About the Process You want to use the Commutative Property of Addition to find an expression equivalent to 111+189. How can you tell if another expression is the result of using the Commutative Property of Addition? Use the Commutative Property of Addition to write an expression equivalent to 111+189. Then find the value of this equivalent expression.

A. The value of the expression is different from the value of original expression B. The numbers are in the same places as in the original expression.
C. The numbers have switched places from where they were in the original expression.
D. The operation changes from addition to multiplication

Answer 1

The Commutative Property of Addition allows us to switch the order of numbers when adding. Therefore, 189 + 111 is an equivalent expression to 111 + 189 as they both yield the same result, 300. Therefore, the correct one is option c.

Step-by-step explanation:

The Commutative Property of Addition tells us the order in which we add numbers doesn't affect the result. So, an equivalent expression to 111 + 189 using the Commutative Property of Addition is 189 + 111. We can verify this by finding the sum of both expressions. Adding 111 + 189 gives us 300. Similarly, adding 189 + 111 also gives us 300. So, both expressions are equivalent. When comparing these expressions to check if they are the result of using the Commutative Property of Addition, the key is to look for the numbers in the expression having switched places (Option C).
