Jason used the commutative property to write an expression that is equivalent to 3
4
+ 5.6b + 9.
3
4
+ 5.6b + 9 is equivalent to 9.0 + 56b + 3.4.

Jason is not correct  as Jason changed the terms.

Step-by-step explanation:

Given the expression 34+5.6b+9.Jason used the commutative property to write the above expression changed to 9.0 + 56b + 3.4

We have to tell Jason work is correct or not.

Commutative property states that order does not matters but the terms remains same i.e a+b=b+aJason change the expression 34+5.6b+9 to 9.0 + 56b + 3.4here, Jason change the terms as well as order Jason is not correct  as Jason changed the terms.
