Answer :
Answer: No.
Step-by-step explanation:
The commutative property of addition tells that it does not matter if we change the order of the addends , the sum remains the same.
Actual expression [tex]\frac{4}{5}+6.9y-8[/tex]
Rewrite this by using only + sign as
[tex]\frac{4}{5}+6.9y+(-8)[/tex]
We can see that the first term is [tex]\frac{4}{5}[/tex] not [tex]\frac{-4}{5}[/tex] and the last term is -8 not 8.
⇒ Maggie changed the signs of the numbers.
Hence Maggie didn't apply the commutative property correctly .
