Ada is showing her work in simplifying (5.9 - 1.8) - 6.2 + 4.1. In which step did Ada make an error? Step 1: (5.9 - 1.8) - 6.2 + 4.1 Step 2: 5.9 + (-1.8 - 6.2) + 4.1 (associative property) Step 3: 5.9 - 8 + 4.1 Step 4: 5.9 + 4.1 - 8 (associative property) Step 5: 10 - 8 = 2 Step 2; she wrote associative instead of commutative Step 2; she wrote associative instead of distributive Step 4; she wrote associative instead of commutative Step 4; she wrote associative instead of distributive
