What is the number rounded too?
6.594
i just want to confirm. because 6 people said 6,
and 5 said 7. i think its 7

The correct estimation for this would be 7

Yes, you are correct! This answer would be rounded to 7.

Some people don't understand(even textbooks, too) that you round any value with a .5 to the higher integer. And since .594 is bigger than .5, 
6.594 is definitely rounded to 7.
