Tom is showing his work in simplifying (5.2 – 8.5) – 0.5 + 6.8. in which step did tom make an error? step 1: : (5.2 – 8.5) – 0.5 + 6.8 step 2: 5.2 + (–8.5 – 0.5) + 6.8 (distributive property) step 3: 5.2 – 9 + 6.8 step 4: 5.2 + 6.8 – 9 (commutative property) step 5: 12 – 9 = 3 step 2; he wrote distributive instead of commutative step 2; he wrote distributive instead of associative step 4; he wrote commutative instead of associative step 4; he wrote commutative instead of distributive
