Question
Hello:

Is the following calculation correct?  

1. 4% X $1000.00 = 4 X 1% X $1000.00 = 4 X (1% X $1000.00) = 4 X $10.00 = $40.00

2. Can 4% be expressed as 4 X 1%?

I think that the commutative property of multiplication allows this to occur.

I thank you for your reply.

Answer
Yes 4% is equivalent to 4 x 1%. You did not use any property, and not the commutative property. If you had written the problem in the following way you could say you used the associative property of multiplication.
4% X $1000.00 = (4 X 1%) X $1000.00 = 4 X (1% X $1000.00) = 4 X $10.00 = $40.00
