Are there any answer choices? I would say 1,000.

The best estimate for 60.94 would be 61. This is because when rounding a number to the nearest whole number, if the decimal portion is 0.5 or greater, the whole number is rounded up. In this case, 0.94 is closer to 1 than to 0, so rounding up to 61 would be the most accurate estimate.
9 is the best estimate whole number
If you know the number is 7128 I do not understand why on earth anyone would want to estimate it!
The best estimate would, of course, be 249.
The best estimate is, obviously, the exact value, which is 217557 since any other estimate will be inferior.Since the operation is multiplication a workable estimate is obtained by rounding one number down and the other one up. This would give 3100*70 = 217000.
Since sqrt(52) is an irrational number, the best estimate is √52. Any decimal estimate can be improved by adding another digit so none can be BEST.
28.57.1 is a number with two decimal places!
The front end estimate is 600. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 558 to 1 trillion, I would estimate it as 0. If I had to add 558 to 0.0000000001, I would use the number as given - not use an estimate.Also, if I had to divide 558 by 5, I would estimate it as 560 since 560/5 = 112 whereas if I had to divide it by 30 I would go for 570 since 570/30 = 19.
It is 0.58, of course. The number line is not simply for integers!
None, since 57 is NOT an irrational number.
Yes, 50.4 can be estimated. In this case, you would round it to the nearest whole number, which would be 50. This is a common estimation technique when dealing with decimal numbers.
