first round off the two numbers you are dividing to the nearest one. For example 9.5/1.5, round it off to 10/2 which will equal to 5.
An estimate is an educated guess. Approximate and round off mean "about".
14,000
5499. To round to the nearest thousand, the hundreds digit would be the decider: if 5 or more it would round up, 4 or less would round down. Need to round down, so the hundreds digit must be 4. The tens and units make no difference, so have them as large are possible, namely 9 each, to give: 5499 as the largest whole number that rounds to 5000 to the nearest 1000. A quick way is to observe 1000/2 = 500, so need to add 1 less than this (499) to the number and it will round down, that is 5000 + 1000/2 - 1 = 5000 + 500 - 1 = 5499.
It is 4.486

The nearest gram is in the ones column, so we must look at the tenths column (the first number on the right of the decimal). If this number if 5 or higher then we must round up and report the value as 1.0 g or if it is lower than 5 then we report the answer as 0.0. All other numbers are irrelevant. In this case (0.[5]3525) the number we are concerned about (in the square brackets) is 5, therefore we round up and the answer is 1.0 g.
Round off to the nearest cent, means round off to the nearest hundredths or round off to two decimal.
3000
4 g
if you round off to the nearest one then its 41, if you round off to the nearest ten, it is 40.

549 and 450 rounded off the nearest hundred is 500
