I would not recommend estimating 1-digit numbers.
I estimate that the nearest whole number to 5 is either 4 or 6.
380/5 = 76
2.2360...
$395.20/5
0.4167
5*80 + 5*5 = 400 + 25 = 425
The estimate is 1.
You wouldn't have to estimate for addition, subtraction or multiplication. For division, use 30/5 = 6
An estimate is a guess. But an educated guess For example: 5. 211 + 4.79 Right away you can estimate that the answer is around 10.
The best estimate is always the exact answer since it is always possible to improve upon any other estimate.
