<u>Answer:</u>
The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.
<u>Solution:
</u>
Maya’s expression will generate the correct sum because of the associative property.
Maya wrote the expression ![3+5+4.5](https://tex.z-dn.net/?f=3%2B5%2B4.5)
As per commutative property of addition if we change the order still the sum will be same, which means
Here also, ![(3 + 5) + 4.5 = 8+4.5 = 12.5](https://tex.z-dn.net/?f=%283%20%2B%205%29%20%2B%204.5%20%3D%208%2B4.5%20%3D%2012.5)
Again ![3 + (5+4.5) = 3+9.5 = 12.5](https://tex.z-dn.net/?f=3%20%2B%20%285%2B4.5%29%20%3D%203%2B9.5%20%3D%2012.5)
As both the results are same, hence this is meeting the commutative property of addition.
