Answer: I only have an answer for the first question, but I think its true .
I'm not sure though so I would clarify it .
Step-by-step explanation:
The reason why I think its true because, 8.4 is also equal to 8.40 . Also, if 8.4 was the answer to something and you put: 8.40 you would still be right .
Hope you get this right!
