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.
d. he wrote associative instead of distributive in step 2.
