Answer 1

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

Answer 2

It's C. Medal.

Answer 3

how do you know

Answer 4

Associative Property: The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis.

Step 4 doesn't deal with associative property, it deals with the commutative property.

Commutative Property: The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
