)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
He wrote identity instead of commutative in Step 4.
He wrote associative instead of commutative in Step 2.
He wrote identity instead of distributive in Step 4.
