Maya wrote the expression 3 + 5 + 4.5 to represent the total distance that she traveled. Which statement best describes Maya's expression?

Maya's expression will generate the correct sum because of the associative property

Maya's expression will generate the correct sum because of the commutative property

Maya's expression will generate the wrong sum because she violated the associative property

Maya's expression will generate the wrong some because she violated the commutative property​

Answer 3

major hint: notice how Maya did not write the numbers in order (going from home to library, the order would be 3, 4.5, 5, so 3 + 4.5 + 5 would be in the right order)

that being said, does 3 + 4.5 + 5 give a different sum than 3 + 5 + 4.5? why or why not?

if in doubt, try adding them up and think about why the sums are/aren't equal.
