BRAINLIEST Andrew is showing his work in simplifying −4.5 + 4.2 + 5.6 − 7.3. Identify any errors in his work or in his reasoning. Step Work Reasoning −4.5 + 4.2 + 5.6 − 7.3 Original problem 1 −4.5 + 4.2 + 5.6 + (−7.3) Additive inverse 2 −4.5 + (−7.3) + 4.2 + 5.6 Commutative property 3 [−4.5 + (−7.3)] + (4.2 + 5.6) Associative property 4 −11.8 + 9.8 Simplify 5 −21.6 Simplify Step 1: He wrote −7.3 incorrectly as + (−7.3). Step 2: He identified changing the order of the numbers as the commutative property, which is incorrect. Step 3: He identified changing the grouping of the numbers as the associative property, which is incorrect. Step 5: He simplified incorrectly.
