Ben is showing his work in simplifying (3.9 − 9.4) − 0.6 + 6.1. identify any error in his work or reasoning. step 1: (3.9 − 9.4) − 0.6 + 6.1 step 2: 3.9 + (−9.4 − 0.6) + 6.1 (associative property) step 3: 3.9 − 10 + 6.1 step 4: 3.9 + 6.1 − 10 (identity property) step 5: 10 − 10 = 0 a. he wrote identity instead of commutative in step 4. b. he wrote associative instead of commutative in step 2. c. he wrote identity instead of distributive in step 4. d. he wrote associative instead of distributive in step 2.

A.He wrote identity property  instead of commutative in step 4.

Step-by-step explanation:

We are given that

Ben is showing his work in simplifying (3.9-9.4)-0.6+6.1

We have to identify error made by Ben in his work

Step 1. (3.9-9.4)-0.6+6.1

Step 2.3.9+(-9.4-0.6)+6.1

Reason: Using associative property of addition

Step 3.3.9-10+6.1

Step 4.3.9+6.1-10

Reason: Using commutative property of addition

Step 5.10-10=0

Therefore, he makes an error in step 4.he wrote identity property instead of commutative property of addition.

Hence, option A is true.

A.He wrote identity property  instead of commutative in step 4.
