Yes but, if you can, you should try to round one up and the other down. Unless that results in rounding well away from the number. For example, 48*62 Exact answer = 2976 If you round 48 up to 50, 62 down to 60 Estimate = 50*60 = 3000 (estimation error = +0.8%) But if you had 48*68 Exact answer = 3264 Round up and down: 50*60 = 3000 (estimation error = -8.1% ) Round down and up: 40*70 = 2800 (estimation error= -14.2%) Round up and up: 50*70 = 3500 (estimation error = +7.2%) The last still has a large error but it is the smallest of the these.
The general rule in rounding up is that that numbers of 5 and above carry forward as 1 onto the next column while numbers of 4 and below are discarded. So, 22164.36113 would round to 22164.361 to three decimal places.
round to 0.140 the ending numbers make you round up and if you must have 3 decimal places keep one ending zero
Sometimes you round up or round down numbers to get close to the correct answer so that you can make sure that your answer is right. If your answer is not close to the rounding down of the numbers you are using then you need to look it over and do it again.
up, so you would round 3.5 to 4.
It is: 3000 because 457 is less than 500 so you round down instead of up
Assuming whole numbers: If rounding to the nearest 10, it would be 3004 If rounding to the nearest 50, it would be 3024 As "to the nearest whatever" increases, so the greatest number also increases. So the greatest "whatever to round to" to produce 3000 must be 3000, that is the question becomes: What is the greatest number that rounds to 3000 to the nearest 3000? Half of 3000 is 1500, so the greatest whole number that rounds to 3000 is 3000 + 1500 - 1 = 4499 (since 3000 + 1500 = 4500 would round up to 6000). Any number such that 1500 ≤ number < 4500 will round to 3000 to the nearest 3000.
You would round the number up - to read 7.040

If the numbers suggest that you should not then it is not better to round.
If the last three digits of any number are equal to or greater than 500, then you round up to the nearest 1000. For example, the number 2573 rounds up to 3000. If the last three digits of any number are equal to or less than 499, then you round down to the nearest 1000. For example, the number 2473 rounds down to 2000. This assumes you are 'rounding up' which is the usual meaning of 'rounding'
3000
To round to the nearest hundred in 8143 you look to the last three digits 143 and if the number are less than 150 than you round down if the numbers are above 150 you round up so the answer to 8143 would be 8100.
