Set all of the denominators to 12 by multiplying 1/3 by 4/4, and 5/6 by 2/2. Now just add them together. 4/12+10/12+5/12=19/12. Or 1 and 7 twelves.

Explain why commutative and associative properties don’t hold true for subtraction and division but the identity properties do ?

nasty-shy [4]

Glad I can help you!!

Answer:

Definition: 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.

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.

If satisfied please leave a review and feel free to give me brainiest.
