Jerry (20+13+15)+(20+47+18)
Layla (20+47+18)+(13+15+20)
Keith (13+20)+(20+47+18)+15
Melinda (13+15+20+20)+(47+18)

How many of the students correctly applied only the associative property to rewrite the expression?
one
two
three
four

Answer with explanation:

⇒Associative property of Addition is applied for three real numbers.For, any three real numbers, A, B and C

≡A+B+C=A+(B+C)=(A+B)+C=(A+C)+B→→→Associative Property of Addition

that is , we can add any two numbers first and then the third number with them.

⇒Also, Commutative Property of Addition of two numbers says that for any two numbers , A and B

≡A+B=B+A

Answer Written by Jerry

→(20+13+15)+(20+47+18)

Answer Written by Layla

→(20+47+18)+(13+15+20)

The Expression Written by Keith and Melinda is Incorrect,because they haven't used the bracket Properly, as associative property says that you can add any two numbers first and then the third number among three numbers.

→→Number of Students who has applied the Associative property Correctly

Answer:

one

Step-by-step explanation:

Associative property of addition states that (a + b) + c = a + (b + c), where a, b and c are some known numbers. This means that you can change the place where parenthesis are without changing the result of the addition. Regardless the four students didn't change the result of the addition, only Melinda used the associative property adequately.
