Blake is showing his work in simplifying (4.6 − 9.2) − 0.8 + 5.4. identify any error in his work or reasoning.

step 1: (4.6 − 9.2) − 0.8 + 5.4
step 2: 4.6 + (− 9.2 − 0.8) + 5.4 (associative property)
step 3: 4.6 − 10 + 5.4
step 4: 4.6 + 5.4 − 10 (associative property)
step 5: 10 − 10 = 0

a.he wrote associative instead of commutative in step 4.
b. he wrote associative instead of commutative in step 2.
c. he wrote associative instead of distributive in step 4.
