Which expression results from using the Commutative Property of Addition to rewrite 9 5/6+ (-6 2/3) +81/6?
A. 9 5/6- 8 1/6 +6 2/3
B. 6 2/3+(-9 5/6)+ 8 1/6
C. -6 2/3+ (-9 5/6)+ 81/6
D. 9 5/6+ 81/6 + (-62/3)
plz help
What's the full quiz answers because this barely helps.
that doesn't help, and........
that is what it is suppose to look like except the (62/3) that is _6 2/3_
9 5/6 must have+ sign
8 1/6 must have + sign
6 2/3 (not 62/3) must have - sign
Need help
To rewrite the expression using the Commutative Property of Addition, we can rearrange the terms while preserving the addition operation.
The Commutative Property of Addition states that changing the order of the addends does not change the sum. So, we can rearrange the terms in any order we want.
Starting with the expression: 9 5/6 + (-6 2/3) + 81/6
Let's rearrange the terms in different orders to see which option matches:
Option A: 9 5/6 - 8 1/6 + 6 2/3
This option does not match the original expression.
Option B: 6 2/3 + (-9 5/6) + 8 1/6
This option matches the original expression after rearranging the terms.
Option C: -6 2/3 + (-9 5/6) + 81/6
This option does not match the original expression.
Option D: 9 5/6 + 81/6 + (-62/3)
This option does not match the original expression.
Therefore, the expression that results from using the Commutative Property of Addition to rewrite 9 5/6 + (-6 2/3) + 81/6 is:
B. 6 2/3 + (-9 5/6) + 8 1/6
Reagan gave you the answer, if you care to read what he said. Only one of the choices contains the original -6 2/3.
review the commutative property. That says that
a+b = b+a
You have a+b+c
so your choices are
a+b+c = b+a+c
a+b+c = a+c+b
You cannot just change the sign of a number and expect the same result.
