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 $\frac{4}{5}+6.9y-8$

Rewrite this by using only + sign as

$\frac{4}{5}+6.9y+(-8)$

We can see that the first term is $\frac{4}{5}$ not $\frac{-4}{5}$ and the last term is -8 not 8.

⇒ Maggie changed the signs of the numbers.

Hence Maggie didn't apply the commutative property correctly .
