The number is already in decimal form so why would you want to estimate it in decimal form???
56.50 - 56.32 = 0.18 You could estimate it as 56.5 - 56.3 = 0.2 but I have no idea why you would want to.
It depends on what you want to do with it. If you want to divide by 8, I would stick with 72. If you want to divide by 5, I'd go for 70 or even 72.5
If you know the number is 7128 I do not understand why on earth anyone would want to estimate it!
Anything you want to measure.
It depends on what I want to do with it. If I want to add 25 to it, I would estimate it as it stands but if I wanted to add 12365458756215486249868815 to it, I would estimate it as 0.In general, I would probably estimate it as 2.2*108.
900 is an estimate. But why would you want to estimate such a simple calculation?
The answer depends on what you want to use the estimate for. If it is being added to 1 billion, I would estimate it as 0. If adding to 25000, I would estimate it as 15000 and if adding to 0.075, I would leave it as it is.

There is no good reason. There are times when you would and times when you would not.

I think the best estimate would be about 80%
If you were a car mechanic and your actual amount came in lower than the estimate, your customer would think he or she got a good deal.
The answer depends on what you wish to do with the estimate. In general, 2.5 will be good, but if you want to divide by 8.3, I would leave it as it is because 2.49/8.3 = 0.3
